ipq40xx: add IPQ4019 SD/MMC controller support

Browse Source 
This commit finally adds support for the built in SD/MMC controller in IPQ4019 SoC.

Controller is supported by the upstream SDHCI-MSM driver with a minor clock setting patch.
Patch is special to the IPQ4019 and cannot be upstreamed.

LDO and SDHCI node are upstreamed, and LDO node is awaiting to be accepted.

IPQ4019 has a built in SD/eMMC controller which is supported by the
SDHCI MSM driver, by the "qcom,sdhci-msm-v4" binding.
So lets add the appropriate node for it.

driver
This introduces the IPQ4019 VQMMC LDO driver needed for
the SD/EMMC driver I/O level operation.
This will enable introducing SD/EMMC support for the built-in controller.

Subject: [PATCH] ARM: dts: qcom: ipq4019: Add SDHCI controller node
IPQ4019 has a built in SD/eMMC controller which is supported by the
SDHCI MSM driver, by the "qcom,sdhci-msm-v4" binding.
So lets add the appropriate node for it.
