[PATCH v5 05/14] hw/sd/sdhci: Include 'pending-insert-quirk' property in quirk bitmask

[Philippe Mathieu-Daudé]

Import Linux's SDHCI_QUIRK_RESTORE_IRQS_AFTER_RESET quirk definition.

Replace 'pending_insert_quirk' boolean (originally introduce in commit
0a7ac9f9e72 "sdhci: quirk property for card insert interrupt status
on Raspberry Pi") by a bit in quirk bitmask.
