[PATCH v3 3/5] ARM: kirkwood: Add HP T5325 thin client

[Andrew Lunn]

Convert the kirkwood t5325-setup.c to mostly device tree for
mach-mvebu. Part of the audio setup needs to remain in C for the
moment until suitable bindings are designed and implemented. So add
board code, triggered by the compatibility string.

Signed-off-by: Andrew Lunn <andrew at lunn.ch>
---
v2:
Remove spaces around KEY_POWER
Correct indentation of help text in Kconfig.
Put dts file into a patch of its own.
v3:
Defer dts Makefile patch to next patch.
