The conversion of all GPIO drivers to using the .set_rv() and
.set_multiple_rv() callbacks from struct gpio_chip (which - unlike their
predecessors - return an integer and allow the controller drivers to
indicate failures to users) is now complete and the legacy ones have
been removed. Rename the new callbacks back to their original names in
one sweeping change.

struct gpio_chip now has callbacks for setting line values that return
an integer, allowing to indicate failures. Convert the driver to using
them.

Clean up the existing export namespace code along the same lines of
commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

IRQ chip data contains a pointer to the GPIO chip. Luckily we have
the pointers the same, but strictly speaking it's not guaranteed.
Even though, still better to fix this.

Unexport suspend/resume handles for the lack of external users and while
at it, make them static, so that they can be discarded by the compiler
if not used (CONFIG_PM_SLEEP=n).
