From: Nicholas Kazlauskas <nicholas.kazlaus...@amd.com>
[Why]
We need hardware reset before hardware init for backdoor loading when
we're reusing the framebuffer memory.
[How]
This doesn't run if the hardware isn't already in reset from software
perspective. The reset function has register level checks so just
remove the software one here.
