[PATCH v2 13/12] ARM: dts: dove: add DT GPU support

[Russell King]

Add DT support for the Vivante GC600 GPU on Marvell Dove platforms.
These nodes default to being disabled unless a platform decides they
should be enabled.

Signed-off-by: Russell King <rmk+kernel at arm.linux.org.uk>

This replaces the previous patch I sent out in error; this version
adds all the DT nodes required.  Also included along with this is a
patch which enables the GPU for Cubox platforms.

This additional patch is in conjunction with my PMU (already merged)
and clock driver patch sets.
