crypto: omap - sha1 & md5 driver



Earlier kernel contained omap sha1 and md5 driver, which was not maintained,
was not ported to new crypto APIs and removed from the source tree.

- implements async  crypto API using dma and cpu.
- supports multiple sham instances if available
- hmac
- concurrent requests
