[net-next] net: cpmac: fix in debug messages

From: Varka Bhadram <varkab@cdac.in>

This patch fix the debug message format. This patch changes to the
commit f160a2d0b524eeebd97a68e2fbb59fad4cdd3fee: net: cpmac: dynamic debug fixes

When we use pr_debug()/netdev_dbg() new lines are inserting in b/w
the values. The format when i use the printk()

These formats used in skb dump and reg dump. This functions
called from the entire code. So this will be enabled all the lines.

Actually it is much better to use a single print for each line.
Otherwise the output can get interleaved.
This might need a temporary buffer.

    Please use pr_cont() instead.

Using pr_cont to continue a <foo>_dbg statement is
ineffective.

There really should be a <foo>_dbg_cont mechanism,
but neither normal pr_debug nor dynamic debug support
such a thing.
