Split omap_prcm_restart() from mach-omap2/prcm.c into SoC-specific variants. These functions need to be able to save the reboot reason into the scratchpad RAM. This implies a dependency on both the PRM and SCM IP blocks, so they've been moved into their own file. This will eventually call functions in the PRM and SCM drivers, once those are created. Vaibhav Hiremath <hvaibhav@ti.com> identified an unused prototype in the first version of this patch - now removed. Tony Lindgren <tony@atomide.com> noted a compile problem with some RMK Kconfigs; resolved in this patch.
