[PATCH 1/3] ARM: davinci: dm646x: fix timer interrupt generation

commit b38434145b34 ("ARM: davinci: irqs: Correct McASP1 TX
interrupt definition for DM646x") inadvertently removed
setting for priority for timer0_12 (bottom half of timer0).
This timer is used as clockevent.

When INTPRIn register setting for an interrupt is left at 0,
it is mapped to FIQ by the AINTC causing the timer interrupt to
not get generated.

Fix it by including an entry for timer0_12 in interrupt
priority map array. While at it, move the clockevent comment to
the right place.
