[Mesa-dev] [PATCH] [Panfrost] [Bifrost] Add a few missing ops to disassembler

[sonicadvance1 at gmail.com]

From: Ryan Houdek <Sonicadvance1 at gmail.com>

Adds Round, RoundEven, and the two Trunc variants to the disassembler.
Additionally adds two control register types that were used with these
instructions.
