Now that PMU enablement code was extended for new Exynos SoCs, it
doesn't look very cohesive and consistent anymore. Do a bit of renaming,
grouping and style changes, to make it look good again. While at it, add
quirks documentation as well.

No functional change, just a refactoring commit.

0-day complains:

drivers/watchdog/s3c2410_wdt.c:94: warning: expecting prototype for Quirk flags for different Samsung watchdog IP(). Prototype was for QUIRK_HAS_WTCLRINT_REG() instead

It doesn't seem to like the idea of documented bit masks. Not really sure
what to do here. I am inclined to ignore it, but I don't want to get flooded
by 0-day complaints until I retire either. Any idea ?

Seems like 0-day thinks this kernel-doc comment is for the first
define only, and thus the comment has wrong format, or something like
that. I tried to follow the same style as GFP_KERNEL and others are
documented.

Anyway, if you don't like 0-day complaints, can you please just
replace kernel-doc comment (/**) with regular comment (/*), by
removing one asterisk in the patch? Or I can re-send the patch
correspondingly -- then just let me know.

Oh, never mind. Let's just hope that 0-day stops complaining at some point.

Just sent v5 for this patch, fixing that 0-day warning properly. Found
info about it here: [1]. So to check that warning, apparently it's
enough to run "make W=n" build, or dry-run for kernel-doc script like
this:

    $ scripts/kernel-doc -v -none drivers/watchdog/s3c2410_wdt.c

Anyway, please take v4 series + v5 for this patch. Hope that'll be all
for 0-day swearing :)
