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

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.

The FlexSPI NOR boot offset does not require any special handling,
the image_offset is correct in either case (0x1000 for FlexSPI NOR

of flash.bin is always 0x58000 on MX8MN/MX8MP, which matches the
CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR * 512 - 0x8000 in case
CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR=0x300, which is always the
