Unfortunately, KERN_CONT doesn't work with dev_foo(),
producing weird messages like:

	tvp5150 6-005c: tvp5150: read 0xf6 = 0xff
	ff

So, we need to get rid of it.

As we're always printing read/write in hexa when dumping
multiple register values, also remove the "0x" from the
read/write debug messages too.

directly, without even specifying the log message level.

Instead of using the v4l_foo() macros, just use the
kernel-wide dev_foo() macros, as there's no good reason

Drivers using dev_foo() macro should not use KERN_CONT, as, internally,
those macros work as if all strings were terminated by a \n. So, doing:

	dev_info(&client->dev, "%s ", client->name);
	printk(KERN_CONT "supports radio, mode is autodetect and autoselect");

Would produce the following output:

	msp3400 6-0044: msp3400
	supports radio, mode is autodetect and autoselect

As there's no good reason to use KERN_CONT, let's rewrite the code
to avoid that, allowing this driver to be converted to dev_foo().

Currently, there's a mess at the V4L2 printk macros: some drivers
use their own macros, others use pr_foo() or v4l_foo() macros,
while more modern drivers use dev_foo() macros.

The best is to get rid of v4l_foo() macros, as they can be
replaced by either dev_foo() or pr_foo(). Yet, such change can
be disruptive, as dev_foo() cannot use KERN_CONT. So, the best
is to do such change driver by driver.

There are replacements for most v4l_foo() macros, but it lacks
a way to enable debug messages per level. So, add such macro,
in order to make the conversion easier.

This driver is old, and have lots of checkpatch violations.
As we're touching a lot on this driver due to the printk
conversions, let's run checkpatch --fix on it, in order to
solve some of those issues.

Also, do a few manual adjustments:
- remove the FSF address and use the usual coding style
  for the initial comments;
- use WARN_ON() instead of BUG_ON();
- remove an unused typedef;
- break a few long lines.

Clock control indirectly requires access to MFC device, so call it only
if we are sure that the device exists in s5p_mfc_release function.
s5p_mfc_remove() calls s5p_mfc_final_pm(), which releases all PM related
resources, including clocks, so any call to clocks related functions
is not valid after s5p_mfc_final_pm().
