ARM: 8540/1: decompressor: use clean-files instead of extra-y to clean files

masahir0y · Russell King · commit 822ec1b6ead2 · 2016-02-22T16:56:30.000Z
This code works fine here, but it is tricky to use "extra-y" for
specifying files to be removed during "make clean".  Kbuild provides
"clean-files" for this purpose.
