Subject: [PATCH v4 01/16] [loongson] eary_printk: Remove existing implementation

From: Wu Zhangjin <wuzj@...ote.com>

This patch will remove the existing implementation of early_printk in
fulong. for this old implementation is based on the board-specific
source code(dbg_io.c), but dbg_io.c is out-of-date:

as the commit: 8d60a903d986ffa26c41f0092320a3b9da20bfaf shows, dbg_io.c
is not needed. it will be removed in the next patch, and the new
implementation of early_printk will be added later.
