OMAP2+: clockdomains: move clockdomain static data to .c files

Browse Source 
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 clockdomain data.
