KEYS: trusted: Introduce NXP DCP-backed trusted keys

DCP (Data Co-Processor) is the little brother of NXP's CAAM IP.
Beside of accelerated crypto operations, it also offers support for
hardware-bound keys. Using this feature it is possible to implement a blob
mechanism similar to what CAAM offers. Unlike on CAAM, constructing and
parsing the blob has to happen in software (i.e. the kernel).

The software-based blob format used by DCP trusted keys encrypts
the payload using AES-128-GCM with a freshly generated random key and nonce.
The random key itself is AES-128-ECB encrypted using the DCP unique
or OTP key.

The DCP trusted key blob format is:
/*
* struct dcp_blob_fmt - DCP BLOB format.
*
* @fmt_version: Format version, currently being %1
* @blob_key: Random AES 128 key which is used to encrypt @payload,
* @blob_key itself is encrypted with OTP or UNIQUE device key in
* AES-128-ECB mode by DCP.
* @nonce: Random nonce used for @payload encryption.
* @payload_len: Length of the plain text @payload.
* @payload: The payload itself, encrypted using AES-128-GCM and @blob_key,
* GCM auth tag of size AES_BLOCK_SIZE is attached at the end of it.
*
* The total size of a DCP BLOB is sizeof(struct dcp_blob_fmt) + @payload_len +
* AES_BLOCK_SIZE.
*/
struct dcp_blob_fmt {
__u8 fmt_version;
__u8 blob_key[AES_KEYSIZE_128];
__u8 nonce[AES_KEYSIZE_128];
__le32 payload_len;
__u8 payload[];
} __packed;

By default the unique key is used. It is also possible to use the
OTP key. While the unique key should be unique it is not documented how
this key is derived. Therefore selection the OTP key is supported as
well via the use_otp_key module parameter.

KEYS: trusted: improve scalability of trust source config

Enabling trusted keys requires at least one trust source implementation
(currently TPM, TEE or CAAM) to be enabled. Currently, this is
done by checking each trust source's config option individually.
This does not scale when more trust sources like the one for DCP
are added, because the condition will get long and hard to read.

Add config HAVE_TRUSTED_KEYS which is set to true by each trust source
once its enabled and adapt the check for having at least one active trust
source to use this option. Whenever a new trust source is added, it now
needs to select HAVE_TRUSTED_KEYS.
