  1. drivers: sdhc: imx_usdhc: move voltage selection to separate function 

    Some USDHC IP instances do not have the voltage control bit present, as
they can only operate at 3.3V. Move code to select 1.8V mode into a
separate helper, and guard the call to UDSHC_SelectVoltage() behind a
feature macro from MCUX SDK.

  3. drivers: sdhc: imx_usdhc: extend reset timeout duration 

    Some instances of the USDHC peripheral take longer to reset, and will
timeout with the previous delay of 100 cycles. Extend this delay to 1000
cycles to resolve this.

  5. boards: nxp: frdm_mcxn947: add support for USDHC0 

    Add support for USDHC0 controller on FRDM_MCXN947 board. This support
was verified using the `tests/subsys/sd/sdmmc` and
`tests/subsys/sd/sdio` testcases. Note that this board does not ship
with the SD header (J12) populated by default, so the user must populate
one.
