dooly: Reduce maximum sensor ODR
In dooly, the accelerometer presented to Android does not use interrupts,
it is polled by the EC. Given the timestamping is not as precise as
interrupt driven one, reduce maximal frequency to meet CTS gaps between
timestamp requirement.
BUG=b:177860358
BRANCH=puff
TEST=Run cheets_CTS_P.x86.CtsSensorTestCases and
cheets_CTS_P.x86.CtsAppTestCases on dooly.
