greybus: audio: Remove GET_TX/RX_DELAY message types
The 'GB_AUDIO_TYPE_GET_TX_DELAY' and 'GB_AUDIO_TYPE_GET_RX_DELAY' are no longer a part of the Greybus Audio Device Class Protocol so remove support for them. The message numbers are not coalesced to prevent compatibility issues between the AP and the module. Testing Done: Played music using a speaker module Signed-off-by: Mark Greer <mgreer@animalcreek.com> Signed-off-by: Greg Kroah-Hartman <gregkh@google.com>
