nb/intel/broadwell: Add an option for where verstage starts
Previously broadwell used a romcc bootblock and starting verstage in
romstage was madatory but with C_ENVIRONMENT_BOOTBLOCK it is also
possible to have a separate verstage.
This selects using a separate verstage by default but still keeps the
option around to use verstage in romstage.
With a separate verstage the romstage becomes an RW stage.
The mrc.bin however is only added to the RO COREBOOT fmap region as it
requires to be run at a specific offset. This means that coreboot will
have to jump from a RW region to the RO region for that binary and
back to that RW region after that binary is done initializing the
memory.
