Subject[PATCH 4/9] ARM: add CONFIG_PHYS_OFFSET default values
Date
For platforms that are not yet converted to ARCH_MULTIPLATFORM,
we can disable CONFIG_ARM_PATCH_PHYS_VIRT, which in turn requires
setting a correct address here.

As we actualy know what all the values are supposed to be based
on the old mach/memory.h header file contents (from git history),
we can just add them here.

This also solves a problem in Kconfig where 'make randconfig'
fails to continue if no number is selected for a 'hex' option.
Users can still override the number at configuration time, e.g.
when the memory visible to the kernel starts at a nonstandard
address on some machine, but it should no longer be required
now.

To make this foolproof, another patch is required in mach-davinci
to prevent a configuration with both DMx and DA8xx enabled but
ARM_PATCH_PHYS_VIRT disabled. The two patches however can be
merged independently as there is no direct dependency between
them.
