The config-devices.mak files are generated by "make", and so they
should be deleted by "make clean".
(This is different from config-host.mak and config-all-disas.mak,
which are created by "configure" and so only deleted by
"make distclen".)
If we don't delete these files on "make clean", then the build
tree is left in a state where it has the config-devices.mak
file but not the config-devices.mak.d file, and make will not
realize that it needs to rebuild config-devices.mak if, for
instance, hw/sd/Kconfig changes.
NB: config-all-devices.mak is also generated by "make", but we
already remove it on "make clean".

I didn't remove the existing 'rm -f $(SUBDIR_DEVICES_MAK)'
from the 'distclean' rules on the basis that config-all-devices.mak
is explicitly removed in both 'distclean' and 'clean', despite
'distclean' depending on 'clean'...
