We currently support OEN read/write for the RZ/G3S SoC but not the
RZ/G2L SoC family (consisting of RZ/G2L, RZ/G2LC, RZ/G2UL, RZ/V2L &
RZ/Five). The appropriate functions are renamed to clarify this and to
match the callback names.
We should also only set the oen_read and oen_write function pointers for
the devices which support these operations. This requires us to check
that these function pointers are valid before calling them.

Account for more than only 23 GPIOs in LPASS Low Power Island pinctrl
generic driver. The previous value 23 was chosen to satisfy existing
SoC-specific drivers. However SM4250 LPI pinctrl uses more than 23 GPIOs
and its probe routine fails on:

return -EINVAL;

In the previous review cycle the regmap cache update code was
questioned since it seems and odd way of using regmap_update_bits().
Thus update the regmap cache modification code to better explain
what it does and why it's done. This is no functional change, but
it's improving code maintainability.

The suffixes of the IRQ identifiers for external interrupts 0-3
are inconsistent:
- "IRQ0" and "IRQ0_A",
- "IRQ1" and "IRQ1_A",
- "IRQ2" and "IRQ2_A",
- "IRQ3" and "IRQ3_B".
The suffixes for external interrupts 4 and 5 do follow conventional
naming:
- "IRQ4A" and IRQ4_B",
- "IRQ5".

- Rename "IRQ[0-2]_A" to "IRQ[0-2]_B",
- Rename "IRQ[0-3]" to "IRQ[0-3]_A".

Based on the NCSI pin table (Table 181) in NCSI spec[1], the reference
clock output pin (RMIIXRCLKO) is not needed on the management controller
side.
To optimize pin usage, add new NCSI pin group that excludes RMIIXRCLKO,
reducing the number of required pins.

The `PIN_CFG_VARIABLE` macro did not indicate the capabilities of a pin
but served as a flag indicating that the pins of a port have different
capabilities.
To better reflect its purpose, move the `PIN_CFG_VARIABLE` macro beside
`RZG2L_SINGLE_PIN` and rename it to `RZG2L_VARIABLE_CFG`. Additionally,
introduce new macros for packing variable port configurations:
- `RZG2L_GPIO_PORT_PACK_VARIABLE(n, a)`: Combines `RZG2L_VARIABLE_CFG`
with `RZG2L_GPIO_PORT_PACK` to handle variable pin configurations
for a packed port.
- `RZG2L_GPIO_PORT_SPARSE_PACK_VARIABLE(m, a)`: Combines
`RZG2L_VARIABLE_CFG` with `RZG2L_GPIO_PORT_SPARSE_PACK` to handle
variable pin configurations for a sparse port.
Due to the above change the configuration macros have been reorganized
as follows:
- Shift the bit positions of `PIN_CFG_NOGPIO_INT`, `PIN_CFG_NOD`,
`PIN_CFG_SMT`, `PIN_CFG_ELC`, and `PIN_CFG_IOLH_RZV2H` down by one
to accommodate the removal of `PIN_CFG_VARIABLE`.

Define `RZG2L_SINGLE_PIN` at the top of the file to clarify its use for
dedicated pins for improved readability.
While at it update the comment for `RZG2L_SINGLE_PIN_PACK` macro and place
it just above the macro for clarity.

Shift the bit masks for `PIN_CFG_PIN_MAP_MASK` and `PIN_CFG_PIN_REG_MASK`,
to accommodate `PIN_CFG_VARIABLE` using `BIT(62)`.
Previously, these bit masks were placed higher up in the bit range, which
did not leave room for `PIN_CFG_VARIABLE` at `BIT(62)`. By adjusting these
masks, we ensure that `PIN_CFG_VARIABLE` can occupy `BIT(62)` without any
conflicts. The updated masks are now:
- `PIN_CFG_PIN_MAP_MASK`: `GENMASK_ULL(61, 54)` (was `GENMASK_ULL(62, 55)`)
- `PIN_CFG_PIN_REG_MASK`: `GENMASK_ULL(53, 46)` (was `GENMASK_ULL(54, 47)`)

Modify the `PIN_CFG_MASK()` macro to be 32-bit wide. The current maximum
value for `PIN_CFG_*` is `BIT(21)`, which fits within a 32-bit mask.

While muxing groups of pins at once can be convenient for large
interfaces, it can also be rigid. This is because the group is set to
all pins which support a particular function, even though not all pins
may be used. For example, the sdhci0 function may be used with a 8-bit
eMMC, 4-bit SD card, or even a 1-bit SD card. In these cases, the extra
pins may be repurposed for other uses, but this is not currently
allowed.
There is not too much point in pin "groups" when there are not actual
pin groups at the hardware level. The pins can all be muxed
individually, so there's no point in adding artificial groups on top.
Just mux the pins like the hardware allows.
To this effect, add a new group for each pin which can be muxed. These
groups are part of each function the pin can be muxed to. We treat group
selectors beyond the number of groups as "pin" groups. To set this up,
we initialize groups before functions, and then create a bitmap of used
pins for each function. These used pins are appended to the function's
list of groups.

rk3328_pin_ctrl uses type of RK3288 which has a hack in

The pinmux bits for GPIO2-B0 to GPIO2-B6 actually have 2 bits width,
correct the bank flag for GPIO2-B. The pinmux bits for GPIO2-B7 is
recalculated so it remain unchanged.
The pinmux bits for those pins are not explicitly specified in RK3328
TRM, however we can get hint from pad name and its correspinding IOMUX
setting for pins in interface descriptions. The correspinding IOMIX
settings for GPIO2-B0 to GPIO2-B6 can be found in the same row next to
occurrences of following pad names in RK3328 TRM.
GPIO2-B0: IO_SPIclkm0_GPIO2B0vccio5
