CFG_TZDRAM_START in OPTEE defines it's load address and is used to
configure the page tables accordingly.

Due to 512MiB DDR limitation of am62x SiP, the memory map has been
modified with OP-TEE moved to bottom of DDR after atf to 0x80080000,
this requires modifications to the OPTEE's CFG_TZDRAM_START.
