This is v2 of my A523 MCU PRCM and NPU support series.

Changes since v1:
- Dropped dual divider clock rate read-back fix that is already merged
- DT binding
  - Moved "r-ahb" clock to the end of the list and added "r-apb0" clock
- Add NPU clk
  - Move .num to after list of clks
- MCU CCU clk driver
  - Added comment for "fixed" dividers in audio PLL clock
  - Corrected variable names for audio PLL divider clocks
  - Added comment for the reversed order of some of the DSP clock's
    parents when compared to the manual
  - Added comments for clocks and resets only found in the BSP driver
  - Corrected register offset for i2s3-asrc and bus-mcu-pwm0 clocks
  - Made "r-ahb" and new "r-apb0" external bus clocks the parents of the
    bus gate clocks, with comments if guessed which one applies
  - Moved .num_clks to after the list of clocks, making it obvious that
    the value needs to be added if more clocks are added to the list
- MCU CCU DT node
  - Enlarged MCU PRCM register range to 0x200
  - Moved "r-ahb" clock to the end of the list and added "r-apb0" clock
- Link to v1
