hal: msm8916: Add single session voice call usecases and devices

Add USECASE_VOICEMMODE1_CALL and USECASE_VOICEMMODE2_CALL usecases
which would be invoked for voice calls on subscription 1 and
subscription 2 respectively in the new voice architecture. PCM
playback and capture devices used by these voice sessions have also
been added both for internal and external codecs.
