servo_v4p1: Initial support for FASTBOOT handling
Hardware support for FASTBOOT is in place, however servo_v4p1 is
currently not exposing an API for servod. Along with improvement for
correct DATA_ROLE handling on servo_v4p1 (in consecutive patch), add
a knob for enabling FASTBOOT.
It is necessary to add complete sequence when enabling FASTBOOT - that
is changing servo DATA_ROLE to DFP. This work will be done in the
future.
