Subject: [PATCH] Show "Device" for remote playback device.

Since we currently don't have access to the name of a remote device,
show a default string "Device" for the device name. In addition,
disable tap on the output switcher.

Fixes: 151486245
Test: manual - cast GPM to home mini and check output switcher in player
for correct icon and string. Additionally, check that tap is disabled.

Change-Id: I31d81f00f0b506b1e2ddc3158043e93cc6db35a8
