cli_classic: Add rpmc command support

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.

Tested on the Winbond W25R128JV as a 'SFDP-capable chip'.

This patch was done to add rpmc command support to flashrom.
This enables users to write root keys to their flash chips while they
flash data on the chip. This might become usefull in the future as rpmc
support is extended in coreboot.
Also adds usefull debug tools to flashrom, which might be usefull in
implementing coreboots rpmc support.
