Subject: [PATCH] mmc: sdhci: do not enable card detect interrupt for gpio cd type
Git-commit: e65bb38824711559844ba932132f417bc5a355e2
Patch-mainline: v5.7-rc1
References: bsc#1111666

Except SDHCI_QUIRK_BROKEN_CARD_DETECTION and MMC_CAP_NONREMOVABLE,
we also do not need to handle controller native card detect interrupt
for gpio cd type.
If we wrong enabled the card detect interrupt for gpio case, it will
cause a lot of unexpected card detect interrupts during data transfer
which should not happen.
