[PATCH] Add option to disable kernel compression

[Christian Ruppert <christian.ruppert@abilis.com>]

Until now, kernel compression can only be disabled by deselecting
HAVE_<compression> in the architecture Kconfig. However, some
users/platforms within the same architecture might want to use
compression while others might want to disable it.
This patch is a solution to the dilemma.
