OMAP4: PRCM: move global reset function for OMAP4 to an OMAP4-specific file
Move the OMAP4 global software reset function to the OMAP4-specific
prm44xx.c file, where it belongs. Part of the long-term process of
moving all of the direct PRCM register writes into lower-layer code.
Also add OCP barriers on OMAP2/3/4 to reduce the chance that the MPU
will continue executing while the system is supposed to be resetting
itself.
