deb4471167 ARM: omap: fix address space warnings from sparse
Moving sram code from plat-omap got the attention of the kernel test robot.

I found a few more places with related warnings because the sram
references are a mix of kernel pointers and __iomem pointers:

mach-omap1/sram-init.c:56:17: warning: cast removes address space '__iomem' of expression
mach-omap1/board-ams-delta.c:667:9: warning: incorrect type in argument 1 (different base types)
mach-omap2/sram.c:78:17: warning: cast removes address space '__iomem' of expression
mach-omap2/omap4-common.c:142:27: warning: incorrect type in assignment (different address spaces)
mach-omap2/omap4-common.c:142:27:    expected void [noderef] __iomem *static [toplevel] sram_sync
mach-omap2/omap4-common.c:142:27:    got void *
mach-omap2/pm34xx.c:113:45: warning: incorrect type in argument 1 (different address spaces)
mach-omap2/pm34xx.c:113:45:    expected void [noderef] __iomem *save_regs
mach-omap2/pm34xx.c:113:45:    got void *extern [addressable] [toplevel] omap3_secure_ram_storage

There is no good solution here, as sram is a bit special in this
regard. Change the annotations to at least shut up the warnings.

11237651e2 ARM: omap: un-merge plat/sram.c
The sram initialization code is the only shared omap1/2 code that
is not a standalone driver, but it is very short. Having two copies
of this code means some duplication of the sources, but actually
saves object code size as it can be inlined better.

f205cfaf6c ARM: OMAP: Move omap1 specific code to local sram.c
Let's make the omap1 specific parts private to mach-omap1.
These should not be in the shared code.
