Added ability to set bus used for hid device tests

When testing HID devices, it was assumed that the bus used would always
be bluetooth. This caused USB hid tests to fail. This patch fixes this
issue by adding a "busType" parameter to the test register file. This
can be either "bluetooth" or "usb" at this time. This will break any
hid test that does not specify a busType.
