sm5803: Enable end of charge interrupts for logs
Currently, it seems that charging is terminated for some reason. This
commit simply enables the end of charge interrupts such that we can
log when this event occurs on the EC console.
BUG=b:160918663
BRANCH=None
TEST=Build and flash waddledee; verify that the EOC interrupts are
detected and that the log prints are emitted when they fire.
