ARM: OMAP2+: board files: use SoC-specific system restart functions

Modify the board files to use the SoC-specific system restart
functions.  At this point it's possible to remove omap_prcm_restart()
from mach-omap2/prcm.c.

While removing the prototypes for the now-unused restart functions, clean
up a few more obsolete prototypes in mach-omap2/clock.h.

-	 * Steps to perform before a Warm reset is trigged:
-	 * 1. enable self-refresh on idle request
-	 * 2. put SDRC in idle
-	 * 3. wait until SDRC goes to idle
-	 * 4. generate SW reset (Global SW reset)
-	 *
-	 * Steps to be performed after warm reset occurs (in bootloader):
-	 * if HW warm reset is the source, apply below steps before any
-	 * accesses to SDRAM:
-	 * 1. Reset SMS and SDRC and wait till reset is complete
-	 * 2. Re-initialize SMS, SDRC and memory
-	 *
-	 * NOTE: Above work around is required only if arch reset is implemented
-	 * using Global SW reset(GLOBAL_SW_RST). DPLL3 reset does not need
-	 * the WA since it resets SDRC as well as part of cold reset.
