Due to the 80-cols restrictions, and latter due to checkpatch
warnings, several strings were broken into multiple lines. This
is not considered a good practice anymore, as it makes harder
to grep for strings at the source code.
As we're right now fixing other drivers due to KERN_CONT, we need
to be able to identify what printk strings don't end with a "\n".
It is a way easier to detect those if we don't break long lines.
So, join those continuation lines.
The patch was generated via the script below, and manually
adjusted if needed.

Most are caused by pointers marked as __iomem when they aren't or not marked as
__iomem when they should.
Also note that readl/writel already do endian conversion, so there is no need to
do it again.
saa7164_bus_set/get were a bit tricky: you have to make sure the msg endian
conversion is done at the right time, and that the code isn't using fields that
are still little endian instead of cpu-endianness.
The approach chosen is to convert just before writing to the ring buffer
and to convert it back right after reading from the ring buffer.
