[PATCH v2 1/2] configs: am64x_evm_a53_defconfig: Move TF-A load address to 0x701c0000

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.

Fixes: defd62ca137b ("arm: dts: k3-am64-main: Update the location of ATF in SRAM and increase its max size")
