remoteproc: Properly represent the attached state
There is a need to know when a remote processor has been attached to rather than booted by the remoteproc core. In order to avoid manipulating two variables, i.e rproc::autonomous and rproc::state, get rid of the former and simply use the newly introduced RPROC_ATTACHED state.
