wifi: cw1200: Convert to GPIO descriptors
The CW1200 uses two GPIOs to control the powerup and reset
pins, get these from GPIO descriptors instead of being passed
as platform data from boardfiles.
The RESET line will need to be marked as active low as we will
let gpiolib handle the polarity inversion.
The SDIO case is a bit special since the "card" need to be
powered up before it gets detected on the SDIO bus and
properly probed. Fix this by using board-specific GPIOs
assigned to device "NULL".
There are currently no in-tree users.
