The E4 revision of the AM64 SKEVM embeds a TPS65219 PMIC,
this enables the necessary options to load and control the
PMIC regulators.

On arm64 systems, recommendation is to use per-cpu timer for time
keeping. Currently AM64 ends up using DM timer as tick timer as driver
is enabled in the config. Drop OMAP DM Timer related configs, this will
switch to using armv8 per-cpu timer as tick timer for A53 SPL/U-Boot.

This converts the following to Kconfig:

CONFIG_SKIP_LOWLEVEL_INIT_ONLY
In order to do this, we need to introduce SPL and TPL variants of these
options so that we can clearly disable these options only in SPL in some
cases, and both instances in other cases.

Kconfig symbols for SYS_MMC_ENV_DEV and SYS_MMC_ENV_PART have been added by
commit 7d08077334. Therefore, move the
definitions of configs to corresponding board defconfig files and enable
configs to save env in eMMC.
Also enable config for FAT write in U-Boot.

Earlier, the region 0x701c0000 to 0x701dffff was firewalled off because of
a bug in SYSFW. In the v2021.05 release of SYSFW this bug has been fixed
and this region can now be used for other allocations.
Therefore, move TF-A's load address to 0x701c0000 and update its location
in the device tree node. Also, increase the size allocated for TF-A to
account for future expansions.

For USB DFU boot mode there is a limitation on the load address of boot
images that they have to be less than 0x70001000. Therefore, move the
SPL_TEXT_BASE address to 0x70000000.
Currently ATF is being loaded at 0x70000000, if the SPL is being loaded at
0x70000000 then ATF would overwrite SPL image when loaded. Therefore, move
the location of ATF to a latter location in SRAM, past the SPL image. Also
rearrange the EEPROM and BSS data on top of ATF.
Given below is the placement of various data sections in SRAM
