The current arasan sdhci PHY configuration isn't compatible
with the PHY on Intel's LGM(Lightning Mountain) SoC devices.

Therefore, add a new compatible, to adapt the Intel's LGM
eMMC PHY with arasan-sdhc controller to configure the PHY.

Applied for next, thanks!

Kind regards
Uffe

Thank you so much for review and applied for next.

Best Regards
Vadivel
