[PATCH] ARM: visit mach-* and plat-* directories when cleaning

[Masahiro Yamada]

When you run "make clean" for arm, it never visits mach-* or plat-*
directories because machine-y and plat-y are just empty.

When cleaning, all machine, plat directories are accumulated to
machine-, plat-, respectively. So, let's pass them to core- to
clean up those directories.
