The exynos4 platform is only dt-based since 3.10, we should convert driver data
and ids to dt-based parsing methods. The rotator driver has a limit table to get
size limit of input picture. Each SoCs has slightly different limit value
compared with any others.
For example, exynos4210's max_size of RGB888 is 16k x 16k. But, others have
8k x 8k. Another example the exynos5250 should have multiple of 2 pixel size
for its X/Y axis. Thus, we should keep different tables for each of them.
This patch also includes desciptions of each nodes for the rotator and specifies
a example how to bind it.

Some vbioses have extra useless entries after "the end" of the table. This is
problematic since all of the vbios I found with this issue redefine the
pwm freq divider to insane levels (52750 Hz instead of 2500), thus breaking
fan management.

The first solution to solve this mess would be to change the length of the
table. The solution I choose was simply to avoid setting the pwm freq twice
as the other redefinitions are harmless with our current parser.

Therm uses 3 ptimer alarms. Two to drive the fan and one for polling the
temperature. When suspending/resuming, alarms will never be fired.
As we are checking if there isn't an alarm pending before rescheduling
another one, we end up never checking temperature or updating the
fan speed.

This commit also adds debug messages to be able to spot more easily
if this case happens again in the future. Sorry for the spam if you
