Changelog v5:
        - added check for key length based on review comment by
	  "Elliott, Robert (Servers)" <elliott@hpe.com>

Changelog v4:
        - scope reduced to cover just SED Opal keys
        - base SED Opal keystore is now in SED block driver
        - removed use of enum to indicate type
        - refactored common code into common function that read and
          write use
        - removed cast to void
        - added use of SED Opal keystore functions to SED block driver

Generic functions have been defined for accessing SED Opal keys.
The generic functions are defined as weak so that they may be superseded
by keystore specific versions.

PowerPC/pseries versions of these functions provide read/write access
to SED Opal keys in the PLPKS keystore.

The SED block driver has been modified to read the SED Opal
keystore to populate a key in the SED Opal keyring. Changes to the
SED Opal key will be written to the SED Opal keystore.
