Merge tag 'cleanup-fixes-for-v3.7' into test_v3.6-rc6_ocb3.7_cff3.7_odaf3.7

These fixes are needed to fix non-omap build breakage for
twl-core driver and to fix omap1_defconfig compile when
led driver changes and omap sparse IRQ changes are merged
together. Also fix warnings for omaps not using pinctrl
framework yet.
