If dram_init_banksize() is called from SPL, the rom_pointer, at that
point, is not correctly initialized. This causes wrong calculation of
DRAM start and size in dram_init_banksize(). The issue became apparent
only in Falcon Mode. Added an extra condition to prevent using
rom_pointer in SPL.

The current bootaux supports i.MX8M and i.MX93, but the name "_M4_"
implies that the SoCs have Cortex-M4. Actually i.MX8MM/Q use Cortex-M4,
i.MX8MN/P use Cortex-M7, i.MX93 use Cortex-M33, so use "_MCU_" in place
of "_M4_" to simplify the naming.

Change boot device logic to also allow environment stored in fat and
in ext4 when booting from SD or eMMC.
As the boot device check for SD and for eMMC was depending on
ENV_IS_IN_MMC being defined, change the ifdef blocks at
env_get_location to use IS_ENABLED instead for all modes, returning
NOWHERE when no valid mode is found.
This solution is based on (with added SPL support):

Currently bootaux only supports to boot M33 core from TCM. Since ATF
has changed to use x2 parameter for M33 image address, update the
bootaux command to use input address, so we can support boot from
any possilbe address like TCM, DDR, Flexspi NOR.
