Simplify the use of the ROM API by using the wrappers that take care
of saving/restoring gd and computing the xor value. This makes the
generated code smaller and the C code easier to read.

The ROM API is thoroughly undocumented, but apparently passing the xor
of the real arguments as an extra argument is required [1]. Also, we
need to do the "save gd/restore gd" dance. These are both error-prone,
and lead to a lot of code duplication.
Since both imx8m[np] and imx8ulp SOCs have this, add a separate
translation unit which is included precisely when the new
CONFIG_IMX8_ROMAPI symbol is set, which provide convenience wrappers
that take care of computing the xor value as well as doing the gd
dance, and that thus have a more intuitive API. Subsequent patches
will make use of these to reduce boilerplate.
[1] One wonders, for example, if the check is only applied to the
lower 32 bits, or if we're implicitly relying on all 64-bit pointer
values we're passing effectively have 0 in the upper 32 bits.

This exposes the struct rom_api, the g_rom_api variable declaration
and the associated #defines to slightly fewer boards: namely, those
IMX8M which are not IMX8MN or IMX8MP. But the latter two are the only
IMX8M* ones where the g_rom_api variable is defined (in imx8m/soc.c),
so that should be fine.

The MTD subsystem has its own small museum of ancient NANDs in a form of
the CONFIG_MTD_NAND_MUSEUM_IDS configuration option. The museum contains
stone age NANDs with 256 bytes pages, as well as iron age NANDs with 512
bytes per page and up to 8MiB page size.
It is with great sorrow that I inform you that the museum is being
decommissioned. The MTD subsystem is out of budget for Kconfig options and
already has too many of them, and there is a general kernel trend to
simplify the configuration menu.
We remove the stone age exhibits along with closing the museum

A common external watchdog circuit is kept alive by triggering a short
pulse on the reset pin. This patch adds support for this use case, while
making the algorithm configurable in the devicetree.
The "linux,wdt-gpio" driver being modified is based off the equivalent
driver in the Linux kernel, which provides support for this algorithm.
This patch brings parity to this driver, and is kept aligned with
the functionality and devicetree configuration in the kernel.
It should be noted that this adds a required property named 'hw_algo'
to the devicetree binding, following suit with the kernel. I'm happy to
make this backward-compatible if preferred.
