internal: Move laptop_ok into board_cfg

Due to how internal is structured around chipset_flash_enable()
entry we need to prepare a crafted programmer_cfg that contains
a board_enable substructure with data derived from the board_enable
subsystem. While this is certainly not perfection, it does make
clear the relationships between board_enable into chipset_flash_enable
and subsequently the overall internal programmer initialisation
in a RAII fashion at the type level over closure upon global
state that is impossible to reason about.

Also flip predicate in report_nonwl_laptop_detected() and
return early with the trivial base-case.

TEST=`$ sudo ./flashrom -p internal --flash-name`.
