Subject: [PATCH 0/2] drm: replace magic nuumbers

amdgpu and radeon do a bit of mucking with the PCIe Link Control 2
register, some of it using hard-coded magic numbers.  The idea here is to
replace those with #defines.

I haven't signed off on these because the first one actually changes the
bits involved because the existing code looks like it might have a typo.
But I have no way to know for sure.

I don't intend the Target Link Speed patch to change anything, so it should
be straightforward to review.
