This adds support for the Imagination Technologies hash
accelerator which provides hardware acceleration for
SHA1 SHA244 SHA256 and MD5 hashes.
Tested on silicon, using testmgr.
Changes from V2:
* This hardware does not support importing a partial hash state,
so the init, update, final and finup have been reworked to use
a fallback driver; only digest remains as hardware accelerated.
* Simplified the driver as a result of the above rework
Changes from V1:
* Addressed review comments from Andrew Bresticker and
Vladimir Zapolskiy
* rebased to current linux-next
