This series adds the missing clock drivers and dts nodes to enable
the GPU on both SM8150 and SM8250.
Note an extra patch [1] is still required for GPU to work on SM8250.
Changes in V2:
* Added "clk: qcom: gcc: fix sm8150 GPU and NPU clocks" to fix the
newly added
SM8150 GPU gcc clocks
* Added "Fixes:" tag to "clk: qcom: clk-alpha-pll: remove
unused/incorrect PLL_CAL_VAL"
* Added yaml schemas to gpucc dt-bindings patches
* Added "clk: qcom: add common gdsc_gx_do_nothing_enable for gpucc
drivers" and changed
gpucc patches to use it.
* Removed CLK_IS_CRITICAL from gpu_cc_ahb_clk
* Added missing rpmh regulator level for sm8250 GPU clock levels
* Use sm8150/sm8250 iommu compatibles in dts
* Add gcc_gpu_gpll0_clk_src/gcc_gpu_gpll0_div_clk_src to gpucc clocks
in dts

Confirmed to be a firmware issue. With older firmware proposed patches
work fine. A patch to support newer firmware releases will be submitted
separately.
