Add support for zpos, alpha and blend properties to RZ/G2L DU
driver as the IP supports all these properties.
It is tested by the below modetest commands:
modetest -M rzg2l-du -s 44@42:1920x1080@AR24 -d -P \
37@42:512x300+200+200@XR15

The RZ/G2L driver utilises the VSPD to read data from input sources.
The rzg2l_du_kms component lists a restricted subset of the capabilities
of the VSPD which prevents additional formats from being used for
display planes.
The supported display plane formats are mapped in rzg2l_du_vsp_formats[].
Extend the rzg2l_du_format_infos[] table with the corresponding mappings
between the supported DRM formats and the formats exposed by the VSP in
rzg2l_du_vsp_formats, maintaining the same ordering in both tables.
The RPF module on VSPD supports various format conversion and send the
image data to BRS(Blend ROP Sub Unit) for further processing.

The rz-du driver uses GEM DMA helpers, but does not implement the
drm_driver .gem_prime_import_sg_table operation. This prevents
importing dmabufs. Fix it by implementing the missing operation using
the DRM_GEM_DMA_DRIVER_OPS_WITH_DUMB_CREATE() helper macro.

Add Kconfig dependency between RZG2L_DU and RZG2L_MIPI_DSI, so that
DSI module has functional dependency on DU. It is similar way that
the R-Car MIPI DSI encoder is handled.
While at it drop ARCH_RENESAS dependency as DRM_RZG2L_DU depend on
ARCH_RZG2L.

The drm_bridge structure contains an encoder pointer that is widely used
by bridge drivers. This pattern is largely documented as deprecated in
other KMS entities for atomic drivers.
However, one of the main use of that pointer is done in attach to just
call drm_bridge_attach on the next bridge to add it to the bridge list.
While this dereferences the bridge->encoder pointer, it's effectively
the same encoder the bridge was being attached to.
We can make it more explicit by adding the encoder the bridge is
attached to to the list of attach parameters. This also removes the need
to dereference bridge->encoder in most drivers.

The continual trickle of small conversion patches is grating on me, and
is really not helping. Just get rid of the 'remove_new' member
function, which is just an alias for the plain 'remove', and had a
comment to that effect:
/*
* .remove_new() is a relic from a prototype conversion of .remove().
* New drivers are supposed to implement .remove(). Once all drivers are
* converted to not use .remove_new any more, it will be dropped.
*/
This was just a tree-wide 'sed' script that replaced '.remove_new' with
'.remove', with some care taken to turn a subsequent tab into two tabs
to make things line up.
I did do some minimal manual whitespace adjustment for places that used
spaces to line things up.
Then I just removed the old (sic) .remove_new member function, and this
is the end result. No more unnecessary conversion noise.
