ARM: dts: qcom: remove overlay regulator node/phandle creation for sun V8

Browse Source 
Sun power grid V8 boards have seen a boot-up issue seemingly caused
by device tree overlays not being applied as expected.  This results
in the rpmh-regulator-mxlvl device not probing correctly as the
proxy-supply property isn't found/resolved.

Correct this issue by moving regulator phandle creation from V8
overlay DTs into the base DT and not creating any regulator nodes
in the overlay DTs (which are duplicates of ones in the base DT).

Change-Id: I2b3515d1ddfa4a9961ef892af61beb8e3afdfd1a
Fixes: 3e728ec361 ("ARM: dts: qcom: add PMIC device support for sun V8 power grid boards")
