ARM: dts: msm: Optimize sdm845 GPU SMMU protection range



SDM845 GPU SMMU range is from 0x05040000--0x05050000.
<0x0504C000--0x0504D000> -- Context Bank 4 (ATOS)
<0x0504D000--0x05050000> -- Context Bank 5/6/7 (HYP owned)

Context Bank 4 is not used by GPU driver.
Context Bank 5/6/7 are already protected by HYP.
Optimize to not protect these using CP_PROTECT_REG.
This will save 2 CP protection ranges.
