OMAP2+: powerdomains: move powerdomain static data to .c files
Static data should be declared in .c files, not .h files. It should be possible to #include .h files at any point without creating multiple copies of the same data. We converted the clock data to .c files some time ago. This patch does the same for the powerdomain data.
