dartmonkey/bloonchipper: Disable low-power-idle in RO

In https://crrev.com/c/2657778 and https://crrev.com/c/2673909
sleeping was explicitly forbidden in RO, in addition to moving
the sleep lines explicitly to RW.

CLs https://crrev.com/c/3012241 and https://crrev.com/c/3052750
bring the sleep lines back to RO (and RW), since they serve to
gate host interface communications when the AP is sleeping.

This CL restores the part of the original two refactoring CLs that
blocks the more complicated low power sleeping.
