Subject: drm/amdgpu/gmc11: implement get_vbios_fb_size()
From: Alex Deucher <alexander.deucher@xxxxxxx>
commit 68518294d00da6a2433357af75a63abc6030676e upstream.
Implement get_vbios_fb_size() so we can properly reserve
the vbios splash screen to avoid potential artifacts on the
screen during the transition from the pre-OS console to the
OS console.
