Add Secret UVC. Bit 0 indicates that version 0x100 is supported,
bit 1 indicates 0x200, and so on.
'supp_add_secret_pcf' notes the supported plaintext flags for
the Add Secret UVC.
'supp_secret_types' notes the supported types of secrets.
Bit 0 indicates secret type 1, bit 1 indicates type 2, and so on.
