[PATCH 12/133] [JAUNTY SRU] ARM.imx51 Freescale:ENGR00108699 [MX51] eMMC4.3 card support

[Brad Figg]

Lower the clock rate in the card inditification procedure,
to fix the cmd crc error and level up the timing compatible.

Ubuntu Note: This is a partial application of the original patch. We do not
             carry either arch/arm/mach-mx35/mx35_3stack.c nor arch/arm/mach-mx37/mx37_3stack.c
	     in our tree.
