[PATCH 5.17 0296/1126] media: camss: vfe-170: fix "VFE halt timeout" error

From: Jonathan Marek <jonathan@marek.ca>

[ Upstream commit 1ce8c48b06f249a9739e36c5d56883f6f49ce047 ]

This function waits for halt_complete but doesn't do anything to cause
it to complete, and always hits the "VFE halt timeout" error. Just delete
this code for now.

Fixes: 7319cdf189bb ("media: camss: Add support for VFE hardware version Titan 170")
