[PATCH] phy: ingenic: Don't disable the supply in exit

[Olivier Louvignes]

The supply is enabled in power_on() and disabled in power_off(); exit()
disabling it again unbalances it. dwc2 powers its PHY off before exiting
it, which warns at every probe on an Ingenic X1600:

  WARNING: ... _regulator_disable
  ...
  ingenic_usb_phy_exit
  phy_exit
  dwc2_lowlevel_hw_disable
  dwc2_driver_probe

Fixes: 31de313dfdcf ("PHY: Ingenic: Add USB PHY driver using generic PHY framework.")

Tested on v7.3 on a HiBy R1 (X1600), whose PHY supply is a dummy
regulator: without this the warning above came at every probe, with it
there is none and USB still enumerates at high speed. Build-tested with
W=1 on phy next.
