This provides GPIO support over SCMI. It is built on top of the
pinctrl-scmi driver. A typical device tree entry might look like
this:
gpio1 {
compatible = "scmi-pinctrl-gpio";
gpio-controller;
#gpio-cells = <2>;
ngpios = <10>;
gpio-ranges = <&scmi_pinctrl 0 8 4>,
<&scmi_pinctrl 4 12 1>,
<&scmi_pinctrl 5 15 1>,
<&scmi_pinctrl 6 17 4>;
pinctrl-names = "default";
pinctrl-0 = <&i2c2_pins>;
};
In this GPIO driver the one thing which is different is that in the
gpio-ranges the first numbers which represent how the pins are exposed
to the users have to start at zero and it can't have gaps.

Add a GPIO controller driver that provides configurable delays when
setting GPIO output values. This is useful for hardware that requires
specific timing delays during power sequencing or GPIO state changes.
The driver wraps underlying GPIO controllers and adds programmable
ramp-up and ramp-down delays specified in microseconds through the
device tree. Each GPIO can have independent delay timings.
Device tree binding matches Linux.

The devm alloc functions that we have may follow the Linux kernel model
where allocations are (almost always) automatically free()'d. However,
quite often we don't enable, in full U-Boot, the tracking and free()'ing
functionality. This in turn leads to memory leaks because the driver
author expects that since the functions have the same name as in the
Linux Kernel they have the same behavior. In turn we then get
functionally correct commits such as commit 00e1fed93c8c ("firmware:
ti_sci: Fix memory leaks in devm_ti_sci_get_of_resource") that manually
add these calls. Rather than manually tracking allocations and
implementing free()s, rework things so that we follow expectations by
enabling the DEVRES functionality (outside of xPL phases).
This turns DEVRES from a prompted symbol to a symbol that must be
select'd, and we now remove our non-managed alloc/free functions from
outside of xPL builds.

In scripts as well as interactively, it's much nicer to be able to
refer to GPIOs via their names defined in the device tree property
"gpio-line-names", instead of the rather opaque names derived from the
bank name with a _xx suffix. E.g.
gpio read factory_reset FACTORY_RESET
if test $factory_reset = 1 ; then ...
versus
gpio read factory_reset gpio@481ac000_16
if test $factory_reset = 1 ; then ...
This is also consistent with the move on the linux/userspace side towards
using line names instead of legacy chip+offset or the even more legacy
global gpio numbering in sysfs.
As dev_read_stringlist_search() depends on both OF_CONTROL and
OF_LIBFDT (which matters for the SPL case), we need some .config
conditional. However, it only adds about ~50 bytes of code to U-Boot
proper, and dm_gpio_lookup_name() most often ends up being GC'ed for
SPL, thus adds no overhead there, so for now make it a hidden symbol
which is merely a convenient shorthand for
CONFIG_IS_ENABLED(OF_CONTROL) && CONFIG_IS_ENABLED(OF_LIBFDT).

For the first time since at least the Allwinner A10 SoCs, the D1 (and
related cores) use a new pincontroller MMIO register layout, so we
cannot use our hardcoded, fixed offsets anymore.
Ideally this would all be handled by devicetree and DM drivers, but for
the DT-less SPL we still need the legacy interfaces.
Add a new Kconfig symbol to differenciate between the two generations of
pincontrollers, and just use that to just switch some basic symbols.
The rest is already abstracted enough, so works out of the box.
