[PATCH v3 4/5] arm64: dts: qcom: eliza: Add CQS SoM UFS variant

[Abel Vesa]

The UFS-equipped Eliza CQS SoM is not described by the existing eMMC
variant. Its storage uses the UFS controller and PHY instead of SDHCI,
and the vreg_l1d supply needs a 1.14-1.26 V constraint instead of 1.8 V.
These differences are on the SoM; both variants use the same EVK carrier.

Describe the UFS controller, PHY supplies and reset GPIO in a dedicated
SoM include, along with the variant-specific vreg_l1d voltage constraint.
Include eliza-cqs-som.dtsi for the shared hardware so neither storage
variant duplicates it or inherits the other's storage configuration.
