If the driver is bool, then please avoid using module.h and anything from
within it. They are either no-ops when built in, or there are non-modular
equivalents available, so it is entirely avoidable, and makes for smaller
and better code.

As long as this information is at the top of the file, then these can
go away too -- just like MODULE_DEVICE_TABLE they are no-op.
