ARM: OMAP4+: Move SRAM data to DT
Use drivers/misc/sram.c driver to manage SRAM on all DT only
OMAP platforms (am33xx, am43xx, omap4 and omap5) instead of
the existing private plat-omap/sram.c
Address and size related data is removed from mach-omap2/sram.c
and now passed to drivers/misc/sram.c from DT.
Users can hence use general purpose allocator apis instead of
OMAP private ones to manage and use SRAM.
