arm64: dts: qcom: sc7180: Fix sc7180-qmp-usb3-dp-phy reg sizes
[ Upstream commit c1124180eb9883891ad2acef89c9d17d6190eab4 ]
As per Dmitry Baryshkov [1]:
a) The 2nd "reg" should be 0x3c because "Offset 0x38 is
USB3_DP_COM_REVISION_ID3 (not used by the current driver though)."
b) The 3rd "reg" "is a serdes region and qmp_v3_dp_serdes_tbl contains
registers 0x148 and 0x154."
I think because the 3rd "reg" is a serdes region we should just use
the same size as the 1st "reg"?
