[PATCH] drm/pci: use PCI_EXP_LNKCAP_SLS_2_5GB/5_0GB instead of hardcoded values

[Jingoo Han]

Use PCI_EXP_LNKCAP_SLS_2_5GB and PCI_EXP_LNKCAP_SLS_5_0GB instead
of hardcoded values for readability. These bit definitions were
added by commit 130f1b8 ("PCI: Add PCIe Link Capability link speed
and width names")
