We were incorrectly shifting the input VGPRs for the instance ID
for chips affected by the LS VGPR init bug (ie. Vega10 and Raven).
When there is no HS threads, the hardware loads the LS VGPR
starting from VGPR 0, so they should be shifted by two.
This fixes some sort of vertex explosion with Squad, Visage, Barn
Finders and probably more titles that use tessellation. Note that
only Vega10 and Raven were affected by this bug.
