Adrian Hunter e557139717 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
