ASoC: ti: omap-hdmi: Re-add dai_link->platform to fix card init

Browse source 
The removed dai_link->platform component cause a fail which
is exposed at runtime. (ex: when a sound tool is used)
This patch re-adds the dai_link->platform component to have
a full card registered.

Before this patch:
$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 1: HDMI [HDMI], device 0: HDMI snd-soc-dummy-dai-0 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0

$ speaker-test -D plughw:1,0 -t sine
speaker-test 1.2.8
Playback device is plughw:1,0
Stream parameters are 48000Hz, S16_LE, 1 channels
Sine wave rate is 440.0000Hz
Playback open error: -22,Invalid argument

After this patch which restores the platform component:
$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: HDMI [HDMI], device 0: HDMI snd-soc-dummy-dai-0 [HDMI snd-soc-dummy-dai-0]
  Subdevices: 0/1
  Subdevice #0: subdevice #0

-> Resolve the playback error.
