x86: Honor 'quiet' command line option in real mode boot decompressor.

Browse source 
This patch lets the early real mode code look for the 'quiet' option
on the kernel command line and pass a loadflag to the decompressor.
When this flag is set, we suppress the "Decompressing Linux... Parsing
ELF... done." messages.
