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/[e-mail]/

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/[e-mail]/

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.

    - 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/[e-mail]

Changes in v5:
- Update ARM64 || COMPILE_TEST in all Kconfig to resolve kismet warnings.
- Fix sparse errors in GPUCC.

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

Changes in v3:
- update PLL configs to use BIT and GENMASK for vco_val and vco_mask for all CCs [Bryan O'Donoghue]
- Link to v2: https://lore.kernel.org/r/[e-mail]

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]
