Main part is copied from ar71xx original driver rb91x_nand
written by Gabor Juhos <juhosg@openwrt.org>.
What is done:
* Support of kernel 5.4 and 5.10,
* DTS support,
* New gpio API (gpiod_*) support.

ath79, lantiq, ipq40xx, ramips all use the OpenWrt-specific gpio-export
functionality. Consolidate the patch that adds it under hack-5.10 since
this logic is obviously not target-specific. For those who want to
disable it, unsetting CONFIG_GPIO_SYSFS symbol will disable this code.

All chipsets from AR7100 up to QCA9563 have three dedicated chipselect
lines for the integrated SPI controller. Remove the number of
chipselects from the platform data, as there is no need to manually set
this to a different value.

Add the SPI_MASTER_GPIO_SS flag for the spi-ath79 driver. Otherwise,
the custom chipselect function is never called. This breaks hardware,
where the three dedicated chipselect lines are used instead of generic
GPIO pins.

This CFI patch was accepted upstream for 5.13. Move it away from under
ath79 and place under backports to be removed in due time.

This updates the NAND driver for MikroTik RB4XX series to work with
kernel 5.10, similarly to the ar934x-nand driver (fb64e2c3).
Support for kernel 5.10 was added to all ath79 subtargets except for the
mikrotik one by commit d6b785d, since patch 920-mikrotik-rb4xx.patch
needed to be reworked. Later, commit f8512661 enabled kernel 5.10 for
the mikrotik subtarget with the nand-rb4xx driver still pending, which
is updated and added back by this patch.
Compile-tested only.

This patch ist not required, as it only has an effect in case the GPIO
descriptors supplied to num-cs are valid.
As this is not the case for ath79, this patch can safely be omitted. The
issue it tried to fix is actually fixed with
0054-spi-sync-up-initial-chipselect-state.

Debugging the SPI CS issue with kernel 5.10 resulted in a better
understanding for the root cause and a proper patch with a better
explanation.
Exchange the old hack patch with a more efficient (and upstreamable)
solution.

This adds the latest version of ofpart commit. It hopefully
1. Doesn't break compilation
2. Doesn't break partitioning
(this time).
It's required to implement fixed partitioning with some quirks. It's
required by bcm53xx, bcm4908, kirkwood, lantiq and mvebu.

This adds Kernel 5.10 support for the generic, nand and tiny subtargets.
The following patch is not contained, as it needs to be reworked:
