[PATCH RFC 00/23] arm64: qcom: enable SM8650 audio without ADSP firmware

[Neil Armstrong]

This patchset adds the necessary plumbing to drive the SM8650 audio
interfaces directly from Linux. This is required for boards like the
Valve Deckard that boot Linux at EL2 without the ADSP audio firmware,
meaning the audio interfaces must be driven directly by the application
processor through lpass-cpu.

Without the ADSP firmware, the LPASS clocks (MI2S bit clocks,
codec macro MCLKs, LPM memory clocks) and memory zones must be
controlled by Linux.

To support this, the series introduces the following changes:
- Bindings: Adds dt-bindings for the SM8650 LPASS core & audio clock
  controllers, LPASS CPU, WSA RX/TX channel ids, and Senary/Septenary MI2S ids.
- Clocks: Adds drivers for the SM8650 LPASS HM, core, audio, and
  AON clock controllers.
- ASoC LPASS core: Prepares the lpass and lpass-cdc-dma drivers to
  handle multiple LPAIFs for I2S ports, allocates and maps LPM buffer
  memory for DAIs, and adds support for the optional WSA interface
  and Senary/Septenary MI2S ports.
- ASoC SM8650: Introduces the SM8650 lpass-cpu variant and allows the
  sc8280xp machine driver to be used with lpass-cpu to keep sound card
  bindings working.
- Device Tree: Refactors the SM8650 dts to move EL1-specific Gunyah nodes
  to a dedicated sm8650-el1.dtsi. Introduces sm8650-lpass-cpu.dtsi for
  boards booting at EL2, and wires up the speakers (Senary MI2S) and
  DMICs (VA macro) on the sm8650-valve-deckard board.
- Defconfig: Enables the SM8650 LPASS CPU driver as a module in arm64 defconfig
