driver core: move dev_has_sync_state() to drivers/base/base.h

Browse Source 
All callers of dev_has_sync_state() are in drivers/base/ and any attempt
to use it outside of driver-core should require good justification, so
there is no need to have it defined in include/linux/device.h.

Thus, move it to drivers/base/base.h.
