ARMv7 may not support large page addressing
ARCH_SUPPORTS_LARGE_PAGE_ADDRESSING allows build environment to
handle specific case when target ARMv7 core only supports 32bit MMU
descriptor mode.
If ARMv7 based platform does not set ARM_CORTEX_Ax=yes, platform
shall define ARMV7_SUPPORTS_LARGE_PAGE_ADDRESSING to enable
large page addressing support.
