[PATCH v6 12/12] MIPS: DTS: jz4780: add sgx gpu node

[H. Nikolaus Schaller]

and add interrupt and clocks.

Tested to build for CI20 board and load a driver.
Setup can not yet be fully tested since there is no working
HDMI driver for jz4780.

Suggested-by: Paul Boddie <paul at boddie.org.uk>
Tested-by: H. Nikolaus Schaller <hns at goldelico.com> # CI20.
