93fff4ce19 ARM: kirkwood: of_serial: fix clock gating by removing clock-frequency
When DT support for kirkwood was first introduced, there was no clock
infrastructure.  As a result, we had to manually pass the
clock-frequency to the driver from the device node.

Unfortunately, on kirkwood, with minimal config or all module configs,
clock-frequency breaks booting because of_serial doesn't consume the
gate_clk when clock-frequency is defined.

The end result on kirkwood is that runit gets gated, and then the boot
fails when the kernel tries to write to the serial port.

Fix the issue by removing the clock-frequency parameter from all
kirkwood dts files.

Booted on dreamplug without earlyprintk and successfully logged in via
ttyS0.

5b60c1453d ARM: Kirkwood: Move common portions into a kirkwood-dnskw.dtsi
A lot of device setup is shared between DNS-320 and DNS-325, move the
definitions into a common include.

Now that we have I2C support in DT, describe the LM75 in
the DT file for the DNS325.

ee24876949 ARM: kirkwood: Define DNS-320/DNS-325 NAND in fdt
Use devicetree to define NAND partitions. Use D-link partition scheme by
default, to be vaguely compatible with their userland.

Changes since last submission (V4):-
* Don't add NAND support then throw it away immediately after [Grant Likely]

9007d10073 ARM: kirkwood: Basic support for DNS-320 and DNS-325
Add support for the DNS-320 and DNS-325. Describe as much as currently possible
in the devicetree files, create a board-dnskw.c for everything else.

Changes since last submission (V3) [Addressing comments by]:-

* One MACH_DLINK_KIRKWOOD_DT for all dtb files [Grant Likely, Jason Cooper]
* Drop brain-dead select "select CONFIG_MTD_OF_PARTS" [Grant Likely]
* Don't add NAND support then throw it away immediately after [Grant Likely]
* Describe purpose of MPP 41, 42 & 49

Changes since last submission (V2):-

* Use IEEE-compliant "okay", rather than "ok" [Scott Wood]
