If CONFIG_PINCTRL_FULL is enabled, never fall back to the simple
implementation. pinctrl_select_state() is called for each device and it
is expected to fail. A fallback to the simple imeplementation doesn't
make much sense.
To keep the return code consistent, we need to change the -EINVAL (which
was ignored before) to -ENOSYS.

At this point, the remaining places where we have a symbol that is
defined as CONFIG_... are in fairly odd locations. While as much dead
code has been removed as possible, some of these locations are simply
less obvious at first. In other cases, this code is used, but was
defined in such a way as to have been missed by earlier checks. Perform
a rename of all such remaining symbols to be CFG_... rather than
CONFIG_...

This breaks chromebook_coral and it is also not how things should work. If
a board needs to bind GPIOs as part of a pinctrl driver this can be done
during the bind step, if needed.
We cannot probe pinctrl devices when binding as a rule, since it cannot be
supported on some platforms.
The bind and probe steps are separate in U-Boot and they should remain
separate.
This reverts commit f9ec791b5e.

The pinctrl datas of uniphier SoCs are the minimal subsets of kernel's one,
and some tables has no data to save the footprint size.
If the board dts tries to match a pin name on no pins defined SoC,
the footprint magic code causes "Synchronous Abort".
This checks if the 'pins' data is valid,
and if empty, avoids the abort with the warning as follows:

Previously, in order for the `pinctrl-*` DT node properties
to be properly processed, the pinctrl's subnodes were limited
to only having the `pinmux` property as well as other additional
properties (slew-rate, bias-disable, etc.). Now, with this patch
the pinctrl driver is made to work similarly to the one from Linux.
It can now distinguish between one subnode and a subnode with multiple
subnodes.

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.
