SM5803: Enable interrupts after setting thresholds
SM5803: Enable interrupts after setting thresholds

Move interrupt enable to the point after configuring the interrupt
thresholds.  This appears to reduce how often the TINT interrupt fires
on init.

BRANCH=None
BUG=b:155436094
TEST=on waddledee, remove power from the board, plug it in, and verify
no TINT interrupt is seen during boot
