ARM: mmp: MMP2 drive strength FAST using wrong value
Drive strength for MMP2 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.
