Adding c10 device type to newly added DeviceAccelerator (#119961)
Follow up to https://github.com/pytorch/pytorch/pull/104364,
A new file got submitted yesterday that is using DeviceType without the c10 namespace. This fixes that. I haven't yet figured out a way to setup a test for this, but I will submit a follow up PR once I figure that out.
