This series adds SD card support for the Qualcomm Glymur SoC and the
Glymur CRD (Customer Reference Design) platform. The changes include
updating voltage regulators to meet SD card requirements, documenting
the new compatible string in device tree bindings, and enabling the SDHC
controller at both the SoC and board levels.

Summary of changes:

Patch 1: Updates the voltage ranges for vreg_l2b_e0 and vreg_l9b_e0 on
the Glymur CRD. Specifically, it reduces the minimum voltage for the
VDDIO supply (l2b) to 1.8V to support high-speed SD card modes and
increases the VDD supply (l9b) for stability.

Patch 2: Documents the Glymur-specific SDHCI compatible string
(qcom,glymur-sdhci) in the sdhci-msm bindings, using qcom,sdhci-msm-v5
as the fallback.

Patch 3: Adds the SDHCI (sdhc_2) node and required pinctrl
configurations to the base Glymur SoC device tree.

Patch 4: Enables the SD card slot on the Glymur CRD by configuring the
regulators and GPIO-based card detection.

Testing: Verified on Glymur CRD hardware.
