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.

This new Armada 38x driver is based on Linux kernel driver. It can set any
pin to any valid function specified in DT like Linux kernel, it provides
support for 'pinmux status -a' command and also for pinctrl_gpio_request().

Armada pinctrl drivers shall not be compiled without the entire pinctrl
framework and thus lack a "depends on" condition, otherwise the driver
will simply not be probed.

To enable support for the Armada 37xx pinctrl driver, we need to
change the Kconfig symbol for the Armada 7k/8k pinctrl driver and its
dependencies to distinguish between both platforms and drivers.

Add a DM port of Marvell pin control driver.
The A8K SoC family contains several silicone dies interconnected
in a single package. Every die is normally equipped with its own
pin controller unit.
There are 2 pin controllers in A70x0 SoC and 3 in A80x0 SoC.
