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.
