Add support to gapless playback by implementing metadata,
next_track, drain and partial drain support.
Gapless on Q6ASM is implemented by opening 2 streams in a single
q6asm stream and toggling them on next track.

Add length to write command packet token so that we can track exactly
how many bytes are consumed by DSP in the command reply.
This is useful in some use-cases where the end of the file/stream
is not aligned with period size.

use flags set by q6asm-dais directly!
This will be useful gapless case where write needs a special flag to indicate
that last buffer.

Each ASM session can have multiple streams attached to it,
current design was to allow only one static stream id 1 per each session.
However for use-case like gapless, we would need 2 streams to open per session.
This patch converts all the q6asm apis to take stream id as argument
to allow multiple streams to open on a single session, This is useful
for gapless playback cases.
Now the dai driver can specify which stream id for each command.
