Currently WA processing for gt is happening in early init API.
It also includes processing of WAs which needs filter based on
hardware engine by looping over number of hardware engines in gt.

However at early init stage hardware engines are not associated
with gt in software which skips processing such WAs.

Example WAs which will be fixed to apply after this change,
"14011060649",
"16010515920",
"16021867713"
