[ALSA] rtctimer: add option to make RTC timer the default sequencer timer
ALSA Core,ALSA sequencer
Add an option to make the RTC timer the default sequencer timer. This
becomes necessary for precise MIDI timing when the system timer runs at
less than 1000 Hz.

+ Say Y here to use the RTC timer as the default sequencer

+ If in doubt, say Y.
