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

Since v1:
  - Add my signed-off-by and Alex's reviewed-by.

Bjorn Helgaas (2):
  drm: replace incorrect Compliance/Margin magic numbers with
    PCI_EXP_LNKCTL2 definitions
  drm: replace Target Link Speed magic numbers with PCI_EXP_LNKCTL2
    definitions
