crypto: engine - remove {prepare,unprepare}_crypt_hardware callbacks
The {prepare,unprepare}_crypt_hardware callbacks were added back in 2016
by commit 735d37b5424b ("crypto: engine - Introduce the block request
crypto engine framework"), but they were never implemented by any driver.
Remove them as they are unused.
Since the 'engine->idling' and 'was_busy' flags are no longer needed,
remove them as well.
