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

Browse Source 
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.

* does not respond to a corrupted read command due to the warm

* SDRC is not sensitive to the warm reset, but the interconnect is
* reset on the fly, thus causing a misalignment between SDRC logic,

* WORKAROUND:
* 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.
