In the first vertion of these patches I've added a MFD driver that
provides API for manipulating shared gpio lines to gpio-latch and nand
drivers. Now I just port gpio-latch and rb91x_nand drivers from ar71xx
to ath79 by adding DTS support and new gpio API (gpiod_*). This way turned
to be more clear and compact. All is working on my RB912UAG-2HPnD. Except a
button and a beeper. The beeper seems is not important thing, but the
button is. The button shares gpio 15 with NAND ALE and NAND IO7, but this
is not easily supported by the current drivers. May be we need ad hoc driver
for button. Or may be there is a more general solution for this problem.
Nevertheless all other seems to be working.

  ath79: add NAND driver for Mikrotik RB91xG series
