ARM: OMAP: Fix handling of errata i727
The errata is applicable on all OMAP4 (4430 and 4460/4470) and OMAP5
ES 1.0 devices. The current revision check erroneously implements this
on all DRA7 varients and with DRA722 device (which has only 1 EMIF instance)
infact causes an asynchronous abort and ends up masking it in CPSR,
only to be uncovered once the kernel switches to userspace.
