The 'pvsecrets import' command imports a protected virtualization secret
into the zkey key repository. Like other key import or key generation
commands, additional information can be associated with the imported key,
such as a textual description, the volume to encrypt with together with
the volume type, the sector size, and a dummy passphrase. You can not
associate a set of APQNs, since a protected virtualization secret does
not need or use a crypto card.
This command only works when running in a secure execution guest.

Add the definitions and utility functions for the PVSECRETS-AES key type.
A PVSECRETS-AES key token contains the secret id of a protected
virtualization secret. It does not contain the key material, just a
reference to the key in the ultravisor.
When such a key token is used to perform crypto operations later on, the
PAES kernel cipher will obtain the protected key belonging to this secret
id with the help of the pkey kernel module.

The 'pvsecrets list' command lists the available protected virtualization
secrets. By default, only those pvsecret types are listed, that can be used
with zkey. If option '--all/-a' is specified, then all pvsecret types are
listed. Nevertheless, pvsecret types not supported by zkey can not be used
with zkey.
This command only works when running in a secure execution guest.

Add functions to interface with the ultravisor device (/dev/uv) when
running in a secure execution guest to retrieve a list of available
secrets.
