Add support for multimedia clock controllers on Qualcomm QCS615 platform.
Update the defconfig to enable these clock controllers.
Global clock controller support

Changes in v8:
- Drop the properties which are already covered as part of gcc.yaml [Krzysztof]
- Drop the RB tag for dt-bindings for Camera clock controller.
- Link to v7: https://lore.kernel.org/r/20250414-qcs615-mm-v7-clock-controllers-v7-0-ebab8e3a96e9@quicinc.com
Changes in v7:
- Update DT bindings for CAMCC, DISPCC, VIDEOCC, GPUCC to remove the
common bindings and add reference to "qcom,gcc.yaml" [Krzysztof]
- Fix the following in the alpha pll code [Bjorn]
- double space removal in clk_alpha_pll_slew_set_rate
- fix the alpha_width from dynamic to 'ALPHA_REG_BITWIDTH'
- cleanup the programming of lower/upper_32_bits of 'alpha'
- update the comment for 'mb()'
- Link to v6: https://lore.kernel.org/all/20250313-qcs615-v5-mm-cc-v6-1-ebf4b9a5e916@quicinc.com/
Changes in v6:
- Remove wrongly RB-By tags which got introduced in v4 and was carried
to v5 as well.
- Adding the reference where the tags were added and dropped.
