[PATCH] atyfb: fix debugging printks

[Mikulas Patocka <mpatocka@xxxxxxxxxx>]

This patch fixes the debugging printks. Use pr_cont, so that the lines are
not broken up. Use printk when starting a new line (a long string of
pr_cont's without any printks causes missing characters in the console
output on sparc).
