Takashi Sakamoto 759a2f40c9 ALSA: oxfw: add an entry for TASCAM FireOne
TASCAM FireOne is based on OXFW971 and ALSA OXFW driver can support it.
These are values of identical registers.

$ ./firewire-request /dev/fw1 read 0xfffff0050000
result: 97100105

$ ./firewire-request /dev/fw1 read 0xfffff0090020
result: 39373100

This commit adds an entry for this model. This model has physical controls
and its MIDI control messages are transferred to second MIDI data stream
multiplexed in one MIDI conformant data channel.
