intel: Drop Tigerlake revision 0 workarounds

Browse Source 
Tigerlake revision 0 is an early stepping that should not be used in
production anywhere, so this code was only used for hardware bringup.
We can drop the unnecessary workarounds.  This also keeps them from
triggering on early steppings of other Gfx12 parts.
