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.

For this board all 16 pins on the SX1509B should be configured as
outputs. Six of them are active-low LEDs. Provide configuration so
those six are initialized to output high, and the remainder to output
low.
Two of the pins control the behavior of the CCS811 gas sensor. By
driving them low on boot the baseline current draw of the board is
reduced by 100 uA.

Update the code configuring pins that control the routing of certain
lines on the board, to take advantage of the introduced possibility
of configuring a pin as output with specified initial state.
Additionally, use `gpio_pin_get_raw` instead of `gpio_pin_get` for
checking the reset pin state, to save a few bytes in flash.
