From: Ciprian Marian Costea <ciprianmarian.costea at oss.nxp.com>

This patchset adds 100mhz & 200mhz pinmux support for uSDHC.
Hence, UHS modes would be supported on NXP boards which enable
usage of VCCQ voltage supply @1.8V by default, with no additional
hardware (board) changes required, such as S32G399A-RDB3.

Changes in V2:
- Added patch for disablement of UHS modes for NXP boards
where VCCQ voltage supply is set to 3.3V by default.
- Fixed S32G2, S32G3 dtb checks warnings related to uSDHC
pinmux renaming.
