The GPIO V2 controller on RK3568 and RK3588 works very similar to
prior generation, main difference is the use of a write mask in the
upper 16 bits and register address offset have changed.
GPIO_VER_ID is a new register at 0x0078 that is used to determine when
the driver should use new or old register offsets and values. Earlier
generation return 0x0 from this offset.
Refactor code and add support for the GPIO V2 controller used in RK3568
and RK3588.

Matching anything that just happens to have the sought-for label as a
prefix is wrong. For example, if the board designer has designated 10
lines for debug purposes, named "debug1" through "debug10", and we are
looking up "debug1", if debug10 happens to be met first during the
iteration we'd wrongly return that.
In theory, this can break existing users that could rely on this
quirk, but OTOH keeping the current broken semantics can cause a lot
of grief for people hitting this in the future and not understanding
why they don't find the line they expect. Considering how few in-tree
defconfigs currently set DM_GPIO_LOOKUP_LABEL (ignoring sandbox, only
four "real" boards), let's fix it before the use becomes more
widespread.

This has been done in order to align the DT of U-Boot with the DT
of Linux. In Linux, a phandle from a '-gpio' DT property is linked
to the pinctrl driver, a single driver that handles both pinctrl
settings and offers GPIO API to callers. On the other hand,
U-Boot redirects such phandle to a corresponding UCLASS_GPIO
driver, because U-Boot offers two different types of drivers
in this case: UCLASS_PINCTRL which handles pin functions and
UCLASS_GPIO which handles gpio requests as a gpio provider.
Due to this, we have two drivers in Uboot, but the Devicetree
has a single node. Thus, just one of the drivers can be probed
for the DT node during platform initialization, before relocation.
Our previous solution in U-Boot was to have a different devicetree:
the gpio node has a subnode for the pinctrl driver, which
is not compliant with Linux ABI. Furthermore, our documentation
for this type of nodes mentions no such gpio compatible.
After this patch, we can no longer add nodes with a gpio
compatible in the DT. Thus, in order to link the pinctrl driver to
the gpio one, a hook to the bind method of the former in U-Boot has
been added and the GPIO related compatibles have been removed to
avoid conflict when compatibles are enumerated and bound to drivers
during platform start before relocation. The bind method will attach
the GPIO driver to the pinctrl DT node so that every phandle coming
from '-gpio' DT properties will be redirected to a valid driver
attached to the pinctrl DT node.

Currently for all Qcom SoCs/boards there are separate compatibles for

bindings which requires only a single compatible "qcom,<SoC name>-pinctrl"
and there is no such compatible property as "qcom,tlmm-<SoC name>".
So fix this inconsistency for Qcom SoCs in order to comply with upstream
DT bindings. This is done via removing compatibles from "msm_gpio" driver
and via binding to "msm_gpio" driver from pinctrl driver in case
"gpio-controller" property is specified for pinctrl node.
