The introduction of ebf0d8dade ("ath79: add new ar934x spi driver")
made the SPI memory unusable on devices with very high spi-max-frequency
(104 MHz).
Here's how the actual clock is calculated: (AHB_CLK/((CLOCK_DIVIDER+1)*2))
where AHB_CLK is a fixed clock (e.g. 200MHz on AR9331) and CLOCK_DIVIDER
is the parameter we can set. Highest clock according to this formula is
AHB_CLK/2 (100MHz, but that didn't work in device tests).
The next possible value is AHB_CLK/4 (50MHz). Speeds between 50 MHz and
100 MHz will be rounded down, so using values higher than 50 MHz does
not provide any benefit.
Consequently, this patch reduces spi-max-frequency for all devices with
values higher than 50 MHz to 50 MHz (effectively, this only affects
devices with 104 MHz before this patch).
Tested on GL.inet GL-AR150:
Boot fails with 104 MHz but is successful with both 50 MHz and 80 MHz
(fast-read), where the latter two yield identical read speeds.

This applies several style adjustments that have been requested in
recent reviews to older DTS files. Despite making the code base more
consistent, this will also help to reduce review time when DTSes
are copy/pasted.
Applied changes:
- Rename gpio-keys/gpio-leds to keys/leds
- Remove node labels that are not used
- Use label property for partitions
- Prefix led node labels with "led_"
- Remove redundant includes
- Harmonize new lines after status property
- Several smaller style fixes

For several devices, wmac MAC address is set from art 0x1002
explicitly by using mtd-mac-address although mtd-cal-data is
pulled from art 0x1000.
With the MAC address in 0x1002, the driver should automatically
use it when reading caldata from 0x1000. Thus, remove the
redundant mtd-mac-address for those devices.

This converts all remaining devices to use interrupt-driven
gpio-keys compatible instead of gpio-keys-polled.
The poll-interval is removed.
Only ar7240_netgear_wnr612-v2 is kept at gpio-keys-polled, as
this one is using ath9k keys.

This patch harmonizes the label and alias for art partitions
across ath79. Since lower case seems to be more frequent, use that
consistently.

>From the Documentation/devicetree/bindings/leds/common.txt:
- default-state : The initial state of the LED. Valid values are "on", "off",
and "keep". If the LED is already on or off and the default-state property is
set the to same value, then no glitch should be produced where the LED
momentarily turns off (or on). The "keep" setting will keep the LED at
whatever its current state is, without producing a glitch. The default is
off if this property is not present.
So setting the default-state of the LEDs to `off` is redundant as `off`
is default LED state anyway. We should remove it as almost every new
PR/patch submission contains this property by default which seems to be
just copy&paste from some DTS file already present in the tree.

Parsing "firmware" partition (to create kernel + rootfs) was implemented
using OpenWrt downstream code enabled by CONFIG_MTD_SPLIT_FIRMWARE. With
recent upstream mtd changes we can do it in a more clean way for DTS
targets. It just requires adding a proper "compatible" string to the
"firmware" partition node.

Use diag.sh version used for apm821xx, ipq40xx and ipq806x, which
supports different leds for the different boot states.
The existing led sequences should be the same as before.

gmac0 is always connected to switch phy4 and mdio1 is always needed.
So add phy handle for eth0 and enable mdio1 by default.
Move fixed-link for gmac1 from device dts to ar9331.dtsi because gmac1 is always connected to builtin switch.

as we use here a generic script hook.
2. Encode "phy0ptp" led trigger in dt of device for all ath79 devices.
