Mary Ruthven 8229bdf775 cr50: stop using the AP uart to detect servo
Now that the AP uart is enabled whenever the AP is on, stop using it to
detect the state of servo. Using the EC uart is good enough and it
simplifies the device state stuff.

BUG=none
BRANCH=none
TEST=on reef and gru verify cr50 can detect servo and disable/enable
cr50 uart at whenever it is attached/detached.
