board: nami: Enable sensors in forced mode

Sensors without interrupt line needs to be in forced mode,
otherwise the EC may not poll them.

BUG=b:73205042
BRANCH=master
TEST=Check with accelrate the ec rate is 100ms by default:
Before:
> accelrate 0
Data rate for sensor 0: 15620
EC rate for sensor 0: 0
Current EC rate: 1000000
Current Interrupt rate: 0

After:
+accelrate 0
Data rate for sensor 0: 15620
EC rate for sensor 0: 100000
Current EC rate: 100000
Current Interrupt rate: 0
