ARM: 7671/1: use Kconfig to select uncompress.h
Following the approach handling DEBUG_LL inclusion, the patch creates
a Kconfig symbol CONFIG_UNCOMPRESS_INCLUDE for choosing the correct
uncompress header. For traditional build, mach/uncompress.h will be
included in arch/arm/boot/compressed/misc.c. For multiplatform build,
debug/uncompress.h which contains a suite of empty functions will be
used. In this way, a platform with particular uncompress.h
implementation could choose its own uncompress.h with this Kconfig
option.
