UPSTREAM: pinctrl: Return -ENOSYS when system call is not available

Update the code to use -ENOSYS, which is the correct error code for an

Also we should not check for a missing operations array as this is not
permitted. For now this can be covered by an assert().

UPSTREAM: dm: pinctrl: fix for introduce PINCONF_RECURSIVE option

Correct the name of the define used CONFIG_IS_ENABLED which is
not aligned with Kconfig name: CONFIG_$(SPL_)PINCONF_RECURSIVE.

The recursive calls is conditional only for UCLASS_PINCONFIG
"pinconfig" driver.
It is always needed to call pinctrl_post_bind for UCLASS_PINCTRL
"pinctrl", the test CONFIG_IS_ENABLED(PINCONF_RECURSIVE) need to
be removed for this driver.

This correct a regression introduced because the same patch is
applied twice times in u-boot-dm branch:
- commit e878b53a79d1 ("dm: pinctrl: introduce PINCONF_RECURSIVE
option")
- commit c20851b3d850 ("dm: pinctrl: introduce PINCONF_RECURSIVE

UPSTREAM: dm: pinctrl: introduce PINCONF_RECURSIVE option

In the Linux pinctrl binding, the pin configuration nodes don't need to
be direct children of the pin controller device (may be grandchildren for
example). This behavior is managed with the pinconfig u-class which
recursively bind all the sub-node of the pin controller.

But for some binding (when pin configuration is only children of pin
controller) that is not necessary. U-Boot can save memory and reduce
the number of pinconf instance when this feature is deactivated
(for arch stm32mp for example for SPL).

This patch allows to control this feature with a new option
CONFIG_PINCONF_RECURSIVE when it is possible for each individual
pin controller device.

UPSTREAM: pinctrl: don't fall back to pinctrl_select_state_simple()

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.

dm: allow limiting pre-reloc markings to spl or tpl

Right now the u-boot,dm-pre-reloc flag will make each marked node
always appear in both spl and tpl. But systems needing an additional
tpl might have special constraints for each, like the spl needing to
be very tiny.

So introduce two additional flags to mark nodes for only spl or tpl
environments and introduce a function dm_fdt_pre_reloc to automate
the necessary checks in code instances checking for pre-relocation
flags.

The behaviour of the original flag stays untouched and still marks
a node for both spl and tpl.
