From: Nicholas Kazlauskas <nicholas.kazlauskas@xxxxxxx> [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.
