drm/amdgpu: Save VCN shared memory with init reset
VCN shared memory is in framebuffer and there are some flags initialized
during sw_init. Ideally, such programming should be during hw_init.
Make sure the flags are saved during reset on initialization since that
reset will affect frame buffer region. For clarity, separate it out to
another function.
Fixes: 1e4acf4d93cd ("drm/amdgpu: Add reset on init handler for XGMI")
