kconfig: autogenerated config_is_xxx macro
this will allow to use to use
if(config_is_xxx())
if(config_is_xxx_module())
in the code instead of
#ifdef CONFIG_xxx
#ifdef CONFIG_xxx_MODULE
and now let the compiler remove the non usefull code and not the
pre-processor
as done in the mach-types for arm as exmaple
