Subject: [PATCH RESEND v2 0/4] DONOTMERGE: ep93xx-clk from ep93xx device
 tree conversion

The goal is to recieve ACKs.

This is a fraction of v9 "ep93xx device tree conversion" series:

https://lore.kernel.org/all/20240326-ep93xx-v9-0-156e2ae5dfc8@maquefel.me/

The clk driver for ep93xx was converted to AUX device, as suggested
originally by Stephen Boyd.

Changes in v2:
- soc: Add SoC driver for Cirrus ep93xx:
  - added __init for ep93xx_adev_alloc(), ep93xx_controller_register()
  - added static, __initconst for pinctrl_names[]
  - clk revision for SPI is now resolved here through differently named
    clk device
  - more verbose Kconfig description

  NOTE: "of" includes are required unfortunately.

- clk: ep93xx: add DT support for Cirrus EP93xx:
  - dropped includes
  - dropped ep93xx_soc_table[]
  - add different named clk and dropped involved includes
  - moved pll's and fclk, hclk, pclk init to separate function
  - fixed ep93xx_clk_ids[] explicit lines

  NOTE: clk_hw_register_div() is clk-ep9xx internal function which uses
  devm.
