[PATCH 1/1] arm64: dts: qcom: sdm845-sony-tama: Enable UFS host controller and PHY

[Shujath Mohd]

Enable the UFS host controller and PHY on Sony Xperia Tama devices.

Provide the UFS reset GPIO and required VCC, VDDA-PHY, and VDDA-PLL
regulators so that the UFS controller and PHY can initialize correctly.

The UFS host controller and PHY have been tested on the Akari, Apollo,
and Akatsuki devices across multiple reboots without observing UFS data
loss or corruption.

Fixes: 30a7f99befc6 ("arm64: dts: qcom: Add support for SONY Xperia XZ2 / XZ2C / XZ3 (Tama platform)")
