broadcom/compiler: don't check for GFXH-1633 on V3D 4.2.x

This has been fixed since V3D 4.2.14 (Rpi4), which is the hardware
we are targetting. Our version resolution doesn't allow us to check
for 4.2 versions lower than .14, but that is okay because the
simulator would still validate this in any case.
