From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx>
Instead of using the driver-specific rtsx_pci_write_config_byte() to update
the PCIe Link Control Register, use pcie_capability_write_word() like the
rest of the kernel does. This makes it easier to maintain ASPM across the
PCI core and drivers.
No functional change intended. I missed this when doing 3d1e7aa80d1c
("misc: rtsx: Use pcie_capability_clear_and_set_word() for
PCI_EXP_LNKCTL").
