[PATCH 11/11] ARM: dts: Add PCLK to the Aspeed watchdogs

[Linus Walleij <linus.walleij@linaro.org>]

This adds the PCLK clock to the Aspeed watchdog blocks.
I am not directly familiar with the Aspeed clocking, but
since the IP is derived from Faraday FTWDT010 it probably
has the ability to run the watchdog on the PCLK if
desired so to obtain the frequency from it, it needs to
be present in the device tree, and for completeness the
PCLK should also be referenced and enabled anyways.

Take this opportunity to add the "faraday,ftwdt010"
compatible as fallback to the watchdog IP blocks.
