ALSA: emu10k1: factor out snd_emu1010_load_dock_firmware() 

Pulled out of the next patch to improve its legibility.

As the function is now available, call it directly from
snd_emu10k1_emu1010_init(), thus making the MicroDock firmware loading
synchronous - there isn't really a reason not to. Note that this does
not affect the AudioDocks of rev1 cards, as these have no independent
power supplies, and thus come up only a while after the main card is
initialized.

As a drive-by, adjust the priorities of two messages to better reflect
their impact.
