[PULL v2 01/21] Makefile: Fix config-devices.mak not regenerated when Kconfig updated

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

When hw/$DIR/Kconfig is changed, the corresponding generated
hw/$DIR/config-devices.mak is not being updated.
Fix this by including all the hw/*/Kconfig files to the prerequisite
names of the rule generating the config-devices.mak files.

Fixes: e0e312f3525a (build: switch to Kconfig)
