Add new parameter vgpu_types_device_addresses_mapping

To support multiple vgpu types configuration, add new
parameter `vgpu_types_device_addresses_mapping` where vgpu-type
is key and list of device_addresses are value.

Also deprecate `enabled_vgpu_types` parameter and instead
use newly added parameter.
