audio/msm7x30: Use q5v2_msm_audio_mvs_frame struct

Otherwise a packet size of 640, which 7x30 modem doesn't support,
will be used. 7x30 expects a packet size of 320.

Was changed in AudioHardware::AudioStreamOutDirect::write, but
seems to have been forgotten here.

audio/msm7x30: Only use earpiece when specified.

There are a few cases where the audio gets routed to earpiece, while it should
be at the speaker mode. To fix this, always default to speaker mode and only use
earpiece when it is specified.
