ASoC: mxs-sgtl5000: Configure the dai_links as unidirectional
On a mx28 board, running "aplay -l" and "arecord -l" results in the following:
$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: mxssgtl5000 [mxs_sgtl5000], device 0: Playback sgtl5000-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: mxssgtl5000 [mxs_sgtl5000], device 1: Capture sgtl5000-1 []
Subdevices: 1/1
Subdevice #0: subdevice #0
$ arecord -l
**** List of CAPTURE Hardware Devices ****
card 0: mxssgtl5000 [mxs_sgtl5000], device 0: Playback sgtl5000-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: mxssgtl5000 [mxs_sgtl5000], device 1: Capture sgtl5000-1 []
Subdevices: 1/1
Subdevice #0: subdevice #0
,which is not correct because we got a capture device listed in aplay and a
playback device listed in arecord.
On mx28 there are two serial audio interface ports (SAIF0 and SAIF1) and each
one of them are unidirectional.
Allow to specify a dai link as 'playback_only' or 'capture_only', which suits
well for this case.
After this change we can correctly report the capabilities as follows:
$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: mxssgtl5000 [mxs_sgtl5000], device 0: HiFi Playback sgtl5000-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0
$ arecord -l
**** List of CAPTURE Hardware Devices ****
card 0: mxssgtl5000 [mxs_sgtl5000], device 1: HiFi Capture sgtl5000-1 []
Subdevices: 1/1
Subdevice #0: subdevice #0
Also tested playback and capture on the mx28evk board.
