Changes in v2:
  The patch series is based on v6.7-rc1. You can simply review or test the
  patches at the link [2].
  - Squashed the patch adding clock definitions with the patch adding the
    binding for the clock controller.
  - Updating dt-binding for syscon, remove oneOf for property compatible;
    define clock controller as child of syscon.
  - DTS changes: merge sg2042-clock.dtsi into sg2042.dtsi; move clock-frequency
    property of osc to board devicethree due to the oscillator is outside the
    SoC.
  - Fixed some bugs in driver code during testing, including removing warnings
    for rv32_defconfig.
  - Updated MAINTAINERS info.
