Converts the usdhc driver to the new gpio api. Updates the device tree for the mimxrt1050_evk board to set appropriate active high/low polarity for the power and card detect pins. Note that the driver doesn't actually support interrupts yet. It initializes a gpio callback for the card detect pin, but never actually enables the gpio interrupt. This incomplete behavior is left as-is, since the purpose of this patch is only to convert the driver to the new gpio api, not to add new features. Signed-off-by: Maureen Helm <maureen.helm@nxp.com>
