758a4d1766 ath79: add AR934x NAND Flash Controller driver
This patch contains updated driver for Atheros NAND Flash Controller
written originally by Gabor Juhos for ar71xx (aka 'ar934x-nfc').
ath79 version has adapted to work with kernel 4.19 and Device Tree.
It has also been renamed to 'ar934x-nand' to avoid confusion with
Near-Field Communication technology.
Controller is present on Atheros AR934x SoCs and required for accessing
internal flash storage on routers like Netgear WNDR4300.
This port preserves all NAND programming code while moving platform
configuration to Device Tree and replacing some kernel functions marked
for retirement by 4.19.
Suitable definition is included in 'ar934x.dtsi' ('nand@1b000200' section).

Most important changes to ar71xx version are:
* old kernel sections of code removed
* 'bool swap_dma' provided by platform data is now set by boolean DT
  property 'qca,nand-swap-dma'
* board-supplied (mach-*.c code) platform data removed - its elements
  become either unused, redundant or replaced by DT methods (like reset)
* IRQ is reserved by devm_request_irq() so free_irq() is not needed anymore
* calls to deprecated nand_scan_ident() + nand_scan_tail() function pair
  replaced by using recommended nand_scan() with attach_chip() callback
* ECC is set to hardware by default, can be overriden by standard DT
  'nand-ecc-*' properties (software Hamming or BCH are other options)

This driver has been successfully tested on Netgear WNDR4300 running
experimental ath79 OpenWrt master branch.

f65501e1c2 ath79: ar93xx/qca95xx: move gmac/wmac/pcie node out of apb bus
according to functional block diagram in datasheet, these devices
don't belong to apb bus.
Move these nodes out to match datasheet description.

8dde11d521 ath79: dts: drop "simple-mfd" for gmacs in SoC dtsi
With a proper probe deferring for ag71xx we don't need to explicitly
probe mdio1 before gmac0.
Drop all "simple-mfd" in SoC dtsi so that gmac orders can be the same
as ar71xx.
This makes eth0/eth1 order the same as those in ar71xx, which means
we don't need a migration script for this anymore and we can merge
incorrectly split gmac/mdio driver back together.

f6c99241ba ath79: ar934x: Update dts for current ag71xx driver
Enable mdio1 by default because mdio1 is needed when eth1 is enabled.

PS: If a ar9341 device has only one port and you only want to use gmac0,
change compatible of gmac1 to "syscon", "simple-mfd" in dts.
