Speaking of the workarounds, where do we stand with at least landing the
split out of init_workarounds_ring()?

Rebuilding the invariant wa_regs[] on every reset is annoying, and how
many of the general mmio need to be reemitted everytime? I would dearly
like to get the flow of the gt/context workarounds improved.
