The "/dts-v1/;" identifier is supposed to be present once at the
top of a device tree file after the includes have been processed.
In ath79, we therefore requested to have in the DTS files so far,
and omit it in the DTSI files. However, essentially the syntax of
the parent ath79.dtsi file already determines the DTS version, so
putting it into the DTS files is just a useless repetition.
Consequently, this patch puts the dts-v1 statement into the parent
ath79.dtsi, which is (indirectly) included by all DTS files. All
other occurences are removed.
Since the dts-v1 statement needs to be before any other definitions,
this also moves the includes to make sure the ath79.dtsi or its
descendants are always included first.

SPI Flash chip supports up to 33 MHz wihout fast read opcode.
Available frequencies are 112.5, 56.25, 37.5, 28.125, 22.5 etc.
This patch increases the nominal maximum frequency to 33 MHz,
reaching an effective increase from 22.5 to 28.125 MHz.
Formula to calculate SPI frequency:
Freq = 225 MHz / 2 / div
Before:
$ time dd if=/dev/mtd1 of=/dev/null bs=8M

$ time dd if=/dev/mtd1 of=/dev/null bs=8M
0+1 records in
0+1 records out

[minor commit message adjustments]

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
