Waiting for the PHY complete flag to clear when releasing the PHY
ownership was add in

commit ddec3627

 ("drm/i915: Wait for TypeC PHY complete flag to clear in safe mode")

This isn't required by the spec, the vague idea was to make the
handshake with the firmware more robust, without actual evidence for
when it would be needed. Checking this again, the flag doesn't clear on
ICL until after the PHY's PLL is disabled and the flag is permanently
set on ADL-P. To avoid the spurious timeout messages in dmesg, just
remove this wait.
