[ARM] pxa: mmc: add 2nd host controller support for pxa3xx
This patch is to add the second mmc controller support for pxa3xx. It's valid for pxa3[0|1|2]0. On zylonite, the second controller has no slot. Signed-off-by: Bridge Wu <bridge.wu@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
