ARM: mmp: PXA910 drive strength FAST using wrong value
Drive strength for PXA910 is a 2 bit value but because of the mapping in
plat-pxa/mfp.h needs to be shifted up one bit to handle real
location in mfp registers. (MMP2 and PXA910 drive strength start
at bit 11 while PXA168 starts at bit 10).
Values 0, 1, 2, and 3 effectively need to be
0, 2, 4, and 6 to fit into register. 8 does not work.
