ARM: OMAP2+: PRM: split PRM functions into OMAP2, OMAP3-specific files
Move OMAP3xxx-specific PRM functions & macros into prm3xxx.[ch] and OMAP2xxx-specific macros into prm2xxx.h. (prm2xxx.c will be created by a subsequent patch when it's needed.) Move basic PRM register access functions into static inline functions in prm2xxx_3xxx.h, leaving only OMAP2/3 hardreset functions in prm2xxx_3xxx.c. Also clarify the initcall function naming to reinforce that this code is specifically for the PRM IP block. This is in preparation for the upcoming powerdomain series and the upcoming move of this code to drivers/.
