The dprintk() macro relies on continuation lines. This is not
a good practice and will break after commit 56387331
("Merge branch 'printk-cleanups").

So, instead of directly calling printk(), use pr_foo() macros,
adding a \n leading char on each macro call.

Continuation lines without KERN_CONT won't work anymore.
However, the way dprintk() was defined leads to the usage
of continuation lines, with should be avoided when possible.

So, redefine those macros.

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.

This driver uses a weird, non-standard macro to print errors.
It allows hiding all messages, including error ones, with doesn't
seem a good idea.

Instead, replace it to pr_foo(), and, for error messages,
use pr_err().

The remaining messages were previouly classified as notice,
info or debug, but they all looked like debug messages.

So, add a dprintk() macro using the "verbose" modprobe
argument to select what will be displayed.

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().

There are no need to set up the PM callbacks (runtime and system) unless
they are being used. It also causes compiler warnings about unused
functions.

Silence the warnings by making them available for CONFIG_PM (runtime
callbacks) and CONFIG_PM_SLEEP (system sleep callbacks).

The driver depended on CONFIG_PM to be functional. Let's remove that
dependency, by enable the runtime PM resourses during ->probe() and
update the device's runtime PM status to reflect this.

Since gsc_m2m_resume() always returns 0, convert it to a void instead.

Instead of having separate functions that fetches, prepares and
unprepares the clock, let's encapsulate this code into ->probe().

This makes error handling easier and decreases the lines of code.
