[PATCH] drm/amdgpu: GC_9.4.3 requires at least 280MB TMR

[Amber Lin]

On GC_9.4.3, if atombios reports TMR size less than 280MB, firmware area
will be overwritten by driver or user application use. Remove !adev->bios
condition since reserve_size is initialized as 0, it'll fail into
else if (!reserve_size) condition.
