accel/qaic: Increase number of in_reset states
'in_reset' holds the state of the device. As part of bringup, the device
needs to be queried to check if it's in a valid state. Add a new state
that indicates that the device is coming up, but not ready for users
yet. Rename to 'dev_state' to better describe the variable.
