[PATCH v2 08/11] drm/amd: Request GFX9 microcode during IP discovery

From: Mario Limonciello
Date: Wed Dec 28 2022 - 11:35:22 EST


If GFX9 microcode is required but not available during early init, the
microcode framebuffer will have already been released and the screen will
freeze.

Move the request for GFX9 microcode into the IP discovery phase
so that if it's not available, IP discovery will fail.
