[PATCH 2/3] drm/panthor: Explicitly include page.h for the {virt, __phys)_to_pfn() defs

[Boris Brezillon]

Something on arm[64] must be including <asm/page.h>, but things fail
to compile on sparc64. Make sure this header is included explicitly
so this driver can be compile-tested on all supported architectures.
