Subject: init/Kconfig: add option to disable kernel compression
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.
