Linus Walleij f3d0d8d938 mtd: nand: gpio: Convert to use GPIO descriptors
There is exactly one board in the kernel that defines platform data
for the GPIO NAND driver.

Use the feature to provide a lookup table for the GPIOs in the board
file so we can convert the driver as a whole to just use GPIO
descriptors.

After this we can cut the use of <linux/of_gpio.h> and use the GPIO
descriptor management from <linux/gpio/consumer.h> alone to grab and use
the GPIOs used in the driver.

I also created a local struct device *dev in the probe() function
because I was getting annoyed with all the &pdev->dev dereferencing.
