powerpc: Remove arch specific byteswappers from the MXC MMC driver
When the MXC MMUC driver is used on a Freescale MPC512x machine, it
contains some additional byteswapping code (I'm assuming this is a
workaround for a hardware defect). This uses the ppc specific st_le32()
function, but there's no reason not to use the generic swab32() function
instead. gcc is capable of generating the efficient ppc byte-reversing
load/store instructions without the arch-specific helper.
This patch, therefore, switches to the generic byteswap routine.
