[PATCH 07/31] ARM: Makefile: descend into mach-* for cleaning

[Sascha Hauer <s.hauer@pengutronix.de>]

When you run "make clean" for arm, it never visits mach-* directories
because machine-y is just empty. With this files generated with extra-y
like the .k3cfg files are not cleaned.

When cleaning, all machine directories are accumulated to machine-, so
let's pass them to common- to clean up those directories.
