crypto: caam - determine whether CAAM supports blob encap/decap
Depending on SoC variant, a CAAM may be available, but with some futures
fused out. The LS1028A (non-E) SoC is one such SoC and while it
indicates BLOB support, BLOB operations will ultimately fail, because
there is no AES support. Add a new blob_present member to reflect
whether both BLOB support and the AES support it depends on is
available.
These will be used in a follow-up commit to allow blob driver
initialization to error out on SoCs without the necessary hardware
support instead of failing at runtime with a cryptic
caam_jr 8020000.jr: 20000b0f: CCB: desc idx 11: : Invalid CHA selected.
