arm64: KASAN depends on !(ARM64_16K_PAGES && ARM64_VA_BITS_48)
On KASAN + 16K_PAGES + 48BIT_VA
arch/arm64/mm/kasan_init.c: In function ‘kasan_early_init’:
include/linux/compiler.h:484:38: error: call to ‘__compiletime_assert_95’ declared with attribute error: BUILD_BUG_ON failed: !IS_ALIGNED(KASAN_SHADOW_END, PGDIR_SIZE)
_compiletime_assert(condition, msg, __compiletime_assert_, __LINE__)
Currently KASAN will not work on 16K_PAGES and 48BIT_VA, so
forbid such configuration to avoid above build failure.
