mmc: sdhci-esdhc-imx: add NXP S32N79 support
Add support for the uSDHC controller found in NXP S32N79 automotive SoCs,
which reuse the existing sdhci-esdhc-imx driver with slice difference.
Compared with s32g2/s32g3, needn't set ESDHC_FLAG_SKIP_CD_WAKE flag
because s32n79 does not have this limitation.
