[ARM] Fix decompressor serial IO to give CRLF not LFCR
As per the corresponding change to the serial drivers, arrange for ARM decompressors to give CRLF. Move the common putstr code into misc.c such that machines only need to supply "putc" and "flush" functions. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
