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

[Li Tony-r64360]

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
