Subject: [PATCH v2 1/1] arm64: dts: qcom: sm8350-sagami: usb qmp phy node - add 'vdda-pll-supply' & 'vdda-phy-supply'

As suggested by Bjorn during review of [1], the 'vdda-pll-supply' &
'vdda-phy-supply' supplies denote the power for the bus and the
clock of the usb qmp phy and are used by the qcom qmp phy driver.

So, its safe to assume that the two regulators are the same as on
the MTP. So let's wire them up in the same way as the MTP.

In absence of the same 'make dtbs_check' leads to following warnings:

arch/arm64/boot/dts/qcom/sm8350-sony-xperia-sagami-pdx215.dt.yaml:
 phy-wrapper@...9000: 'vdda-phy-supply' is a required property

arch/arm64/boot/dts/qcom/sm8350-sony-xperia-sagami-pdx215.dt.yaml:
 phy-wrapper@...9000: 'vdda-pll-supply' is a required property

Changes since v1:
-----------------
- v1 can be found here: https://www.spinics.net/lists/linux-arm-msm/msg108467.html
- Fixed the commit message to read usb qmp phy instead of ufs phy (which
  was introduced erroraneously in the commit log).
