Comment incorrectly cites errata 39
E39. SDIO: SDIO Devices Not Working at 19.5 Mbps
Should be errata 38
E38. MEMC: Memory Controller hangs when entering Self Refresh Mode.

This is already done automatically for many other ARM platforms by the
ARM core code, but since pxa is using the .map_io callback, it needs to
call it explicitely for earlyprintk support.
