7a839dbab1 misc: rtsx: Add short delay after exit from ASPM
DMA transfers to and from the SD card stall for 10 seconds and run into
timeout on RTS5260 card readers after ASPM was enabled.

Adding a short msleep after disabling ASPM fixes the issue on several
Dell Precision 7530/7540 systems I tested.

This function is only called when waking up after the chip went into
power-save after not transferring data for a few seconds. The added
msleep does therefore not change anything in data transfer speed or
induce any excessive waiting while data transfers are running, or the
chip is sleeping. Only the transition from sleep to active is affected.

3d1e7aa80d 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.
