mmc: rtsx_pci_sdmmc: ignore broken write-protect on ThinkPad X260
The Realtek RTS522A card reader in the Lenovo ThinkPad X260
(subsystem 17aa:504a) incorrectly reports inserted SD cards as
write-protected.
This causes the MMC core to expose the card as read-only:
mmcblk0: mmc0:aaaa SN256 238 GiB (ro)
and /sys/block/mmcblk0/ro reports 1.
Setting MMC_CAP2_NO_WRITE_PROTECT makes the card writable again.
Limit the quirk to the affected Lenovo subsystem.
