[PATCH] switch remaining serial drivers to initcalls

From: Christoph Hellwig <hch@lst.de>

All drivers that compile on ppc with CONFIG_ISA set (= all but
some m68-only drivers), I looked at the compile warnings very
closely and there are no new warnings or even errors this time :)

drivers/char/Makefile needed to be reordered big time to keep
the intialization order the same.
