arm64: cache: Merge cachetype.h into cache.h
cachetype.h and cache.h are small and both obviously related to caches. Merge them together to reduce clutter. Acked-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Will Deacon <will.deacon@arm.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
