rpmc: add rpmc commands feature

Added optional support for all the commands specified in JESD260.
Added a new optional dependency to openssls libcrypto.
Added parsing for the rpmc parameter sfdp table.
Added necessary rpmc parameter information to flashchips struct and the
flash hardening feature to enable rpmc commands.

Enables future use of these commands in the cli_client and also
libflashrom.
