clk: ux500: fix bit error
This fixes a bit error in the U8500 clock implementation: the unused p2_pclk12 registered at bit 12 in periphereral group 6 was defined as using bit 11 rather than bit 12. When walking over and disabling the unused clocks in the tree at late init time, p2_pclk12 was disabled, by effectively clearing the but for p2_pclk11 instead of bit 12 as it should have, thus disabling gpio block 6 and 7.
