[PATCH CFT] ARM:SHMOBILE: Enable AUTO_ZRELADDR by default

[panchaxari]

This patch enables AUTO_ZRELADDR as default config to Renasas R-Mobile and
SH-Mobile platforms.

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 R-Mobile and SH-Mobile platforms to evaluate the
changes on the board and comment, as I dont have the board for testing, and
also requesting an ACK.
