This change uses the appropriate _cansleep or non-sleeping API for reading GPIO card detect state. This allows users with GPIOs that never sleep to avoid a warning when certain quirks are present. The sdhci controller has an SDHCI_QUIRK_NO_CARD_NO_RESET, which indicates that a controller will not reset properly if no card is inserted. With this quirk enabled, mmc_get_cd_gpio is called in several places with a spinlock held and interrupts disabled. gpiod_get_raw_value_cansleep is not happy with this situation, and throws out a warning. For boards that a) use controllers that have this quirk, and b) wire card detect up to a GPIO that doesn't sleep, this is a spurious warning. This change silences that warning, at the cost of pushing this problem down to users that have sleeping GPIOs and controllers with this quirk.
