On MikroTik RB91x board series a reset key shares SoC gpio
line #15 with NAND ALE and NAND IO7. So we need a custom
gpio driver to manage this non-trivial connection schema.
Also rb91x-nand needs to have an ability to disable a polling
of the key while it works with NAND.
While we've been integrating rb91x-key into a firmware, we've
figured out that:
* In the gpio-latch driver we need to add a "cansleep" suffix to
several gpiolib calls,
* When gpio-latch and rb91x-nand fail to get a gpio and an error
is -EPROBE_DEFER, they shouldn't report about this, since this
actually is not an error and occurs when the gpio-latch probe
function is called before the rb91x-key probe.
We fix these related things here too.

On ar71xx, it was possible to overwrite the name of the spi-nor mtd device
identifier using the flash_platform_data which each mach-*.c could adjust
for its devices. A similar feature was introduced for mtd-physmap in
devicetree's. The property linux,mtd-name can be used to set the name and
provide a stable identifier for mtdpart from the bootloader.
But this feature is not yet available upstream for spi-nor devices which
also might receive their partition layout from the bootloader. But the
OpenWrt pistachio support for this property can simply be imported into
ath79 to gain this support.

mtd: spi-nor: locking support for MX25L6405D
Macronix MX25L6405D supports locking with four block-protection bits.
Currently, the driver only sets three bits. If the bootloader does not
sustain the flash chip in an unlocked state, the flash might be
non-writeable. Add the corresponding flag to enable locking support with
four bits in the status register.
mtd: spi-nor: disable 16-bit-sr for macronix
Macronix flash chips seem to consist of only one status register.
These chips will not work with the "16-bit Write Status (01h) Command".
Disable SNOR_F_HAS_16BIT_SR for all Macronix chips.

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.
Signed-off-by: David Bauer <mail@david-bauer.net>
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 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
