mmc: sdhci-acpi: enable runtime-pm for device HID INT33C6
sdhci-acpi supports ACPI devices which have compatibility ID
PNP0D40, however it is not possible to know if those devices
will all work correctly with runtime-pm, so that must be configured
per hardware ID.
For INT33C6, several related quirks, capabilities and flags are set:
MMC_CAP_NONREMOVABLE
The SDIO card will never be removable
SDHCI_ACPI_RUNTIME_PM
Enable runtime-pm of the host controller
MMC_CAP_POWER_OFF_CARD
Enable runtime-pm of the SDIO card
MMC_PM_KEEP_POWER
SDIO card has the capability to remain powered up
during system suspend
SDHCI_QUIRK2_HOST_OFF_CARD_ON
Always do a full reset during system resume
because the card may be already initialized having
not been powered off.
Wake-ups from the INT33C6 host controller are not supported, so the
following capability must *not* be set:
MMC_PM_WAKE_SDIO_IRQ
Enable wake on card interrupt
