ARM: make decompressor debug output user selectable
Make the decompressor debug output user selectable, otherwise merely enabling DEBUG_LL causes the decompressor to become board specific, thereby preventing a multi-platform kernel from booting. Enabling DEBUG_LL doesn't cause the kernel itself to become platform specific unless EARLY_PRINTK is enabled, or one of the debugging routines is added in a path that results in it being called.
