Add a new compatible to use the sdhc-arasan host controller driver
with the eMMC PHY on Intel's Lightning Mountain SoC.

From: Ramuthevar Vadivel Muruganx <vadivel.muruganx.ramuthevar@linux•intel.com>
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.
