ALSA: usb-audio: Manage number of rawmidis globally
We're going to create rawmidi objects for MIDI 2.0 in a different code from the current code for USB-MIDI 1.0. As a preliminary work, this patch adds the number of rawmidi objects to keep globally in a USB-audio card instance, so that it can be referred from both MIDI 1.0 and 2.0 code.
