[PATCH 1/2] configs: am571x_hs_evm_defconfig: Reserve EMIF memory used by PPA

[Beleswar Padhi]

The AM571x SoC has 1 GB DDR space. As part of normal re-location process
U-Boot copies itself to the top of DDR bank. However, on HS devices, the
top 0x2500000 is used by PPA and is firewalled. This results in an
exception and the boot fails.

Introduce a new defconfig for AM571x HS platforms and set
CONFIG_SYS_MEM_TOP_HIDE to reserve the top 0x2600000 memory (aligned to
2MB as per page size for ARM32) for the same.
