[PATCH] arm64: dts: qcom: qcs6490-rb3gen2: Specify zap region for gpu

[Bjorn Andersson]

Without the zap region defined the enabled GPU will, if able to find the
other firmware files, attempt to initialize itself without the zap
firmware loading, which causes the rb3gen2 to freeze or crash.

Add the zap-shader node and define the memory-region and firmware path
to avoid this problem.
