firewire: core: handle device quirk of TASCAM FW-1884/FW-1804/FW-1082
TASCAM FW-1884/FW-1804/FW-1082 is too lazy to repspond to asynchronous
request at S400. The asynchronous transaction often results in timeout.
This is a problematic quirk.
This commit adds support for the quirk. When identifying the new quirk
flag, then the transaction speed is configured at S200.
