This patch enables AUTO_ZRELADDR as default config to Realview platform.

AUTO_ZRELADDR config enables auto calculation of the decompressed kernel image
address. AUTO_ZRELADDR config is mutually exclusive to ZBOOT_ROM, and also
assumes zImage to be loaded in the first 128MiB from start of memory.

CFT::Call For Testing

Requesting maintainers of Realview platforms to evaluate the changes on the
board and comment, as I dont have the board for testing, and also requesting
an ACK.
