[PATCH v4 08/16] crypto: rsa: include key name hint into CONFIG_CRYPTO_RSA_KEY

[Sascha Hauer]

Set the key name hint in CONFIG_CRYPTO_RSA_KEY. CONFIG_CRYPTO_RSA_KEY
now has the form:

<key_name_hint>:<filename/uri>

This is done in preparation to make CONFIG_CRYPTO_RSA_KEY a list of
keys.

 	  This option should be a filename of a PEM-formatted file containing
 	  X.509 certificates to be included into barebox. If the string starts
 	  with "pkcs11:" it is interpreted as a PKCS#11 URI rather than a file.
+	  If the string starts with a <hint>: prefix, <hint> is used as a key
