[PATCH 4/6] arm64: dts: qcom: pmi8998: add USB Type-C and VBUS regulator nodes

[taygoth]

The PMI8998 PMIC includes a USB Type-C detection block at SPMI offset
0x1300 and a USB OTG VBUS boost converter at offset 0x1100. Both are
left disabled here so that only boards which wire up the connector and
USB role-switch enable them.

The VBUS regulator falls back to the qcom,pm8150b-vbus-reg compatible
because the OTG register layout (CMD_OTG, OTG_CFG, OTG_CURRENT_LIMIT)
is identical to the PM8150B SMB5 block.
