motion_sense: Reduce condition for lid angle calc.
The motion sense task was checking to see that every single motion
sensor was ready (active, initialized, and reading), before performing
the lid angle calculations. This amount of checking is unnecessary.
This commit reduces the condition to only check if the sensors required
for lid angle calculation are ready.
BUG=chrome-os-partner:36132
BRANCH=None
TEST=Build and flash on samus. Verify that the lid still works.
TEST=make -j buildall tests
