soc/intel/braswell: add default option to use public FSP
The current Braswell FSP 1.1 header in vendorcode/intel, for
which there is no publicly available FSP binary, contains silicon
init UPDs which are not found in the publicly available header/binary
in the FSP Github repo. This prevents new boards from being added
which use the public Braswell FSP header/binary.
To resolve this, move the UPDs not found in the public header from
the soc's chip.c to ramstage.c for the boards which use them. Add
a Kconfig option to use the current non-public FSP header and
select it for boards which need it (google/cyan variants); set the
public FSP option as the default. Use the Kconfig option to set
FSP_HEADER_PATH to ensure the correct header is used.
Test: build google/cyan and intel/strago using non-public and
public FSP header/binaries respectively.
