ARM: make decompressor debug output user selectable

Russell King · Russell King · commit 29337b60ab5d · 2017-11-21T14:46:11.000Z
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.
