ARM: 8113/1: remove remaining definitions of PLAT_PHYS_OFFSET from <mach/memory.h>
The platforms selecting NEED_MACH_MEMORY_H defined the start address of their physical memory in the respective <mach/memory.h>. With ARM_PATCH_PHYS_VIRT=y (which is quite common today) this is useless though because the definition isn't used but determined dynamically. So remove the definitions from all <mach/memory.h> and provide the Kconfig symbol PHYS_OFFSET with the respective defaults in case ARM_PATCH_PHYS_VIRT isn't enabled. This allows to drop the dependency of PHYS_OFFSET on !NEED_MACH_MEMORY_H which prevents compiling an integrator nommu-kernel. (CONFIG_PAGE_OFFSET which has "default PHYS_OFFSET if !MMU" expanded to "0x" because CONFIG_PHYS_OFFSET doesn't exist as INTEGRATOR selects NEED_MACH_MEMORY_H.)
