Since this value is fixed at compile time and sometimes based on constants such as ARCH_PHYS_OFFSET, it gets in the way of runtime PHYS_OFFSET and CONFIG_ARM_PATCH_PHYS_VIRT usage. Let's introduce atag_offset which should contains only the relative offset from PHYS_OFFSET instead of an absolute value, in preparation to move all instance of boot_params over to it.
