[PATCH v6 00/27] Add support for MT8196 clock controllers

[Laura Nao <laura.nao@collabora.com>]

This patch series introduces support for the clock controllers on the
MediaTek MT8196 platform, following up on an earlier submission[1].

MT8196 uses a hardware voting mechanism to control some of the clock muxes
and gates, along with a fence register responsible for tracking PLL and mux
gate readiness. The series introduces support for these voting and fence
mechanisms, and includes drivers for all clock controllers on the platform.

Changes in v6:
- Removed unnecessary braces in clk-mux and clk-gate
- Excluded clk26m from the parent lists of vlp_audio_h, vlp_aud_engen1,
  vlp_aud_engen2, and vlp_aud_intbus
- Reordered entries in of_match_clk_mt8196_mdpsys
- Converted mfg_eb clock into a mux with a gate
