The rk3318 is basically a rk3328 with improved gpu,
so add a dtsi based on that.

Please don't add dangling dtsi files.
I'd expect at least a board dts to actually use that and
also the updated gpu node.
From a cursory glance it looks like it gets upgraded from
450-MP2 to 450MP3 or so, so that would at least mean
another set of interrupts.
I'm not sure anything's "improved" - as far as the internet can tell
it's a special low-cost variant of RK3328 for low-end TV box vendors
that Rockchip don't want to talk about. The DTB for my H96 Max 3318
shows no appreciable difference from the BSP DT for RK3328, although I
wouldn't be surprised if some of the unused stuff like the external GMAC
was actually missing or broken. The board itself is the exact same one
used in a lot of other cheap RK3328 boxes (and I mean literally, it's
silkscreened "RK3328_8D4_V1.2").
Thanks to one unexpectedly honest Aliexpress listing I stumbled across,
the "penta-core GPU" apparently translates from TV-box-marketing-speak
to mean Mali-450 MP2 (1GP + 2PP) plus the RGA plus the VOP ;)
