[PATCH 1/4] dt-bindings: gpu: mali-bifrost: Allow up to two clocks

Commit b681af0bc1cc ("drm: panfrost: add optional bus_clock")
added an optional bus_clock to support Allwinner H6 T-720 GPU.
Increase the max clock items in the dt-binding to reflect this.

Bifrost GPU in Rockchip RK3568 SoCs also has a core and a bus clock
and it gets added here in a (very) similar way it was done for
allwinner,sun50i-h6-mali compatible in arm,mali-midgard binding.
