[RFT PATCH] mtd: rawnand: ingenic: move the GPIO quirk to gpiolib-of.c

[Bartosz Golaszewski <brgl@xxxxxxxx>]

From: Bartosz Golaszewski <bartosz.golaszewski@xxxxxxxxxx>

We have a special place for OF polarity quirks in gpiolib-of.c. Let's
move this over there so that it doesn't pollute the driver.

Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski@xxxxxxxxxx>

This is an alternative to the previous patch that instead of replacing
one active-low setter with another, just moves the quirk over to
gpiolib-of.c
