payloads/seabios: Add Hardware IRQ Kconfig

Certain boards require SeaBIOS' HARDWARE_IRQ option to be
deselected in order for the platform to boot. Add a Kconfig
to allow selection of HARDWARE_IRQ enablement, and write to
SeaBIOS' .config file in cases where it needs to be disabled.
Deselect the option for google/rambi variants so they boot
with boards defaults.

Test: build/boot google/clapper, verify board boots vs hanging
at boot menu prompt.
