ALSA: usb-audio: us144mkii: Add PCM core infrastructure
This patch adds the ALSA PCM device infrastructure. It creates a new
PCM device with one playback and one capture stream.
The hardware capabilities (formats, rates, channels) are defined in
`tascam_pcm_hw`. The core PCM operations (`snd_pcm_ops`) for both
playback and capture are implemented, including open, close, hw_params,
prepare, and pointer callbacks.
The trigger callback is a stub for now. This commit allows user-space
applications to interact with the ALSA device, but no audio will be
streamed yet.
