    ARM: 8113/1: remove remaining definitions of PLAT_PHYS_OFFSET from <mach/memory.h> · c6f54a9b
    Uwe Kleine-König authored
    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.)
