Subject: [PATCH v2] arm64: dts: qcom: qcs6490-rb3gen2: Enable UFS

The rb3gen2 has UFS memory, adjust the necessary supply voltage and add
the controller and phy nodes to enable this.

Changes in v2:
- Added missing regulator-allow-set-load and regulator-allowed-modes
- Dropped max-voltage for vreg_l9b_1p2 to it's expected value
- Link to v1: https://lore.kernel.org/r/[email protected]
