[ALSA] rawmidi - move output trigger into a tasklet

Documentation,RawMidi Midlevel
Calling the output trigger callback from another interrupt handler
can lead to unintuitive locking requirements (i.e., spin_lock_irqsave)
in the sound card interrupt handler. Moving the call to the callback
into a tasklet cures this, and has the added benefit that the callback
is called only once if more that one sequencer event has been
delivered in one timer interrupt tick.

[ALSA] fix P16V breakage for non Audigy2 cards

EMU10K1/EMU10K2 driver
The P16V patch unconditionally checks the IPR2 register in the interrupt
handler resulting in infinite loop and system lockup on any non Audigy2
cards. I really hate checking emu->is_audigy and emu->revision in a
fast path like the IRQ handler but I don't see another way.

Also, don't bother allocating/freeing the DMA buffer for P16V unless
it's really present.

This is a critical fix and should trigger an immediate rc2 release IMO.
Currently any emu10k1 users other than Audigy 2 will lock up hard as
soon as they play any sound.
