[PATCH]Disable early console in default to avoid printing boot message twice

From: Li Tony-r64360 <hidden>

The early console is default enable in powerpc 32 now.
This cause the boot message from beginning to console_init() printed
twice.
The early console is useful only when the kernel dead before
console_init.
The patch make the early console optional and disable the early console
in default.
The patch has been tested on mpc8313erdb board

It is also very annoying that the early boot messages are printed twice=20=

on ppc64. Can you include ppc64 in this patch?
