[ Upstream commit 73d4337ed9ceddef4b2f0e226634d5f985aa2d1c ]
commit b38434145b34 ("ARM: davinci: irqs: Correct McASP1 TX interrupt definition for DM646x") inadvertently removed priority setting 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.
