[PATCH] make loglevel related commandline to early_param v2
so we can use them for early console like
console=uart8250,io,0x3f8,115200n8
earlycon=uart8250,io,0x3f8,115200n8
early_printk
otherwise printk(KERN_DEBUG "debug msg") will not print out to console even
"debug" command line is used.
andi point out early_param need to return 0 instead 1.
Ingo had another patch in x86.git to process ignore_loglevel
