Add support for videocc, camcc, dispcc and gpucc on Qualcomm QCS615 platform

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

Global clock controller support
https://lore.kernel.org/all/20241022-qcs615-clock-driver-...

Changes in v9:
- Reuse the qcom,sm6350-camcc.yaml for QCS615 [Vladimir]
	- Still carrying the RB-tag from Krzysztof on the CAMCC DT bindings from (v8)
- Added all the RB-tags received in (v8).

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-con...

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...

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.

    - Drop wrong RB-By from Dmitry(v5)
  -[09/10] clk: qcom: videocc-qcs615: Add QCS615 video clock controller driver
    - R-By from Dmitry and Bryan (v3)
  -[10/10] arm64: defconfig: Enable QCS615 clock controllers
    - Drop wrong RB-By from Dmitry (v5)
- Link to v5: https://lore.kernel.org/r/20250221-qcs615-v5-mm-cc-v5-0-b...

Changes in v5:
- Update ARM64 || COMPILE_TEST in all Kconfig to resolve kismet warnings.
- Fix sparse errors in GPUCC.
- Link to v4: https://lore.kernel.org/r/20250119-qcs615-mm-v4-clockcont...

Changes in v4:
- Drop patch Update the support for alpha mode configuration as this
  patch was picked - https://lore.kernel.org/all/20241021-fix-alpha-mode-confi...
- Update the bindings to include "qcom,gcc.yaml" [Dmitry]

Changes in v3:

- Link to v2: https://lore.kernel.org/r/20241101-qcs615-mm-clockcontrol...

Changes in v2:
- cleanups in clk_alpha_pll_slew_update and clk_alpha_pll_slew_enable functions [Christophe]
- update PLL configs for "vco_val = 0x0" shift(20)  [Bryan O'Donoghue]
- update PLL configs to use lower case for L value  [Dmitry]
- Link parents for IFE/IPE/BPS GDSCs as Titan Top GDSC [Bryan O'Donoghue, Dmitry]
- Remove DT_BI_TCXO_AO from camcc-qcs615           [Dmitry]
- Remove HW_CTRL_TRIGGER from camcc-qcs615         [Bryan O'Donoghue]
- Update platform name for default configuration   [Dmitry]
- Link to v1: https://lore.kernel.org/r/20241019-qcs615-mm-clockcontrol...
