[PATCH v2 07/11] drm/amd: Request MES microcode during IP discovery

[Mario Limonciello <mario.limonciello@amd.com>]

If MES 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 MES microcode into the IP discovery phase
so that if it's not available, IP discovery will fail.
