Subject: [PATCH] arm64: dts: qcom: Fix WiFi supplies on sc7180-idp

The WiFi supplies that were added recently can't have done anything
useful because they were missing the "-supply" suffix.  Booting
without the "-supply" suffix would give these messages:

ath10k_snoc 18800000.wifi: 18800000.wifi supply vdd-0.8-cx-mx not found, using dummy regulator
ath10k_snoc 18800000.wifi: 18800000.wifi supply vdd-1.8-xo not found, using dummy regulator
ath10k_snoc 18800000.wifi: 18800000.wifi supply vdd-1.3-rfa not found, using dummy regulator
ath10k_snoc 18800000.wifi: 18800000.wifi supply vdd-3.3-ch0 not found, using dummy regulator

Let's add the "-supply" suffix.

I don't have an IDP setup but I have a similar board.  Testing on IDP
would, of course, be appreciated.
END
