arm64: dts: freescale: Fix VPU G2 clock

[ Upstream commit b27bfc5103c72f84859bd32731b6a09eafdeda05 ]

Set VPU G2 clock to 300MHz like described in documentation.
This fixes pixels error occurring with large resolution ( >= 2560x1600)
HEVC test stream when using the postprocessor to produce NV12.

Fixes: 4ac7e4a81272 ("arm64: dts: imx8mq: Enable both G1 and G2 VPU's with vpu-blk-ctrl")
