This time it is maybe borderline as it makes sense to see a list of
archs that uses this.
But still I would prefer you did like this:

drivers/ide/Kconfig:

config HAVE_IDE_ARCH_OBSOLETE_DEFAULTS
	bool

config IDE_ARCH_OBSOLETE_DEFAULTS
	depends on HAVE_IDE_ARCH_OBSOLETE_DEFAULTS

And then in each arch Kconfig include:

arch/alpha/Kconfig:
config ALPHA
	select HAVE_ARCH_OBSOLETE_DEFAULTS

And the same for the others.
