misc: rtsx: Use pcie_capability_clear_and_set_word() for PCI_EXP_LNKCTL
Instead of using the driver-specific rtsx_pci_update_cfg_byte() to update the PCIe Link Control Register, use pcie_capability_clear_and_set_word() like the rest of the kernel does. This makes it easier to maintain ASPM across the PCI core and drivers. Remove the now-unused rtsx_pci_update_cfg_byte() and ASPM_MASK_NEG definitions. No functional change intended.
