ARM: imx31: Fix IIM mapping leak in revision check
mx31_read_cpu_rev() maps the IIM registers with of_iomap() to read the
silicon revision, but returns without unmapping the MMIO mapping.
Keep the normalized revision value in a local variable and route the
return path through iounmap() after the revision register has been read.
