arm64: dts: qcom: sm8150-hdk: fix SS USB regulators
[ Upstream commit a509adf05b2aac31b22781f5aa09e4768a5b6c39 ]
The SM8150-HDK uses two different regulators to power up SuperSpeed USB
PHYs. The L5A regulator is used for the second USB host, while the first
(OTG) USB host uses different regulator, L18A. Fix the regulator for the
usb_1 QMPPHY and (to remove possible confusion) drop the
usb_ss_dp_core_1/_2 labels.
