The crypto algorithm modules utilizing the crypto daemon could
be used early when the system start up. Using module_init
does not guarantee that the daemon's work queue is initialized
when the cypto alorithm depending on crypto_wq starts. It is necessary
to initialize the crypto work queue earlier at the subsystem
init time to make sure that it is initialized
when used.

Part of the include cleanups means that the implicit
inclusion of module.h via device.h is going away. So
fix things up in advance.

kcrypto_wq and pcrypt->wq's are used to run ciphers and may consume
considerable amount of CPU cycles. Mark both as CPU_INTENSIVE so that
they don't block other work items.
As the workqueues are primarily used to burn CPU cycles, concurrency
levels shouldn't matter much and are left at 1. A higher value may be
beneficial and needs investigation.

Use dedicated workqueue for crypto subsystem
A dedicated workqueue named kcrypto_wq is created to be used by crypto
subsystem. The system shared keventd_wq is not suitable for
encryption/decryption, because of potential starvation problem.
