drm/radeon: Use RMW accessors for changing LNKCTL2
Convert open coded RMW accesses for LNKCTL2 to use
pcie_capability_clear_and_set_word() which makes its easier to
understand what the code tries to do.
LNKCTL2 is not really owned by any driver because it is a collection of
control bits that PCI core might need to touch. RMW accessors already
have support for proper locking for a selected set of registers
(LNKCTL2 is not yet among them but likely will be in the future) to
avoid losing concurrent updates.
