Why on libdrm ?

As upstream said: amdgpu is never going to be used on noMMU platforms,
and the amdgpu tests are only compiled in when the amdgpu driver is
enabled. From tests/Makefile.am:

if HAVE_AMDGPU
if HAVE_CUNIT
SUBDIRS += amdgpu
endif
endif

So, just make BR2_PACKAGE_LIBDRM_AMDGPU depends on BR2_USE_MMU. Isn't
that sufficient ?

Thanks,

Thomas
