Subject: [PATCH] [PATCH} - revised sdhci: sdhci-pxa only supports mmp2 at this
time - enforce this
sdhci-pxa.c does not handle pxa168 and pxa9xx at this time.
The code does not take into account differences in the private registers
nor other nuances. Restrict support to mmp2 until these issues are
resolved.
This patch is a revision of the previous patch - it uses CPU_MMP2
instead or the MACH_FLINT / MACH_ config variables
