mx51evk: Add CONFIG_REVISION_TAG
FSL 2.6.35 kernel assumes that the bootloader passes the CONFIG_REVISION_TAG information. If this data is not present, the kernel misconfigures the TZIC, which results in the timer interrupt handler never being called, so the kernel deadlocks while calibrating its delay.
