[ARM] mmp: fix for variables in uncompress.h being discarded
Due to commit: 5de813b ARM: Eliminate decompressor -Dstatic= PIC hack The data section will be discarded for the decompressor, thus move the static variables into BSS section by initializing them at run time. Reported-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Eric Miao <eric.y.miao@gmail.com>
