OMAP: voltage: move plat/voltage.h to mach-omap2/voltage.h
At this point in time, there's no reason for this header file to be in plat-omap/include/plat/voltage.h. It should not be included by device drivers, and the code that uses it is currently all under mach-omap2/. Signed-off-by: Paul Walmsley <paul@pwsan.com>
