drm/amdgpu: Fix Vega10 VM initialization
adev->family is not initialized yet when amdgpu_get_block_size is called. Use adev->asic_type instead. Minimum VM size is 512GB, not 256GB, for a single page table entry in the root page table. gmc_v9_0_vm_init is called after adev->vm_manager.max_pfn is initialized. Move the minimum VM-size enforcement ahead of max_pfn initializtion. Cast to 64-bit before the left-shift.
