Use the rproc->power reference count to handle the multi-instance
case, move the state checking for 'stop' and 'detach' under
mutex protection, and remove state checking for 'start'.

Shengjiu Wang (2):
  remoteproc: core: Remove state checking before calling rproc_boot()
  remoteproc: core: Move state checking to remoteproc_core

changes in v2:
- drop 'remoteproc: core: check rproc->power value before decreasing it'
- refine 'remoteproc: core: Remove state checking before changing state'
  split it to two new patches.
