Merge branch 'omap-fixes-urgent' of git://git.linaro.org/people/rmk/linux-arm

This pull request covers the major oopsing issues with OMAP, caused by
the lack of the TWL driver.  Even when the TWL driver is not built in,
we shouldn't oops.

  ARM: omap: fix broken twl-core dependencies and ifdefs
  ARM: omap: fix oops in drivers/video/omap2/dss/dpi.c
  ARM: omap: fix oops in arch/arm/mach-omap2/vp.c when pmic is not found

           Say yes here if you have TWL4030 / TWL6030 family chip on your board.
           This core driver provides register access and IRQ handling
