firmware: coreboot: make coreboot_bus_type const

rbmarliere · Tzung-Bi Shih · commit e3c5df138169 · 2024-02-06T11:56:17.000+08:00
Now that the driver core can properly handle constant struct bus_type, move the coreboot_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
