Power on devices represented by entities in the graph through the pipeline
state using V4L2 graph PM operations instead of what was in the omap3isp

When the Media controller framework was merged, it was decided not to add
pipeline power management code for it was not seen generic. As a result, a
number of drivers have copied the same piece of code, with same bugfixes
done to them at different points of time (or not at all).
Add these functions to V4L2. Their use is optional for drivers.

Change vidioc_s_input() to enable the media source for the newly
selected input.
v4l2-core enables source before calling au0828's vidioc_s_input()
handler. Hence, when input selection changes, media source for the
newly selected input needs to be enabled.

dev->ctrl_input is set in vidioc_s_input() and doesn't get set in
au0828_s_input(). As a result, dev->ctrl_input is left uninitialized
until user space calls s_input.
It works correctly because the default input value is 0 and which is
what dev->ctrl_input gets initialized via kzalloc().
Change to set dev->ctrl_input in au0828_s_input(). Also optimize
vidioc_s_input() to return if the new input value is same as the
current.

This patch adds a binary attribute /sys/class/rc/rc?/wakeup_data which
allows to read / write the wakeup sequence.
In combination with the core extension for exposing the most recent raw
packet this allows to easily define and set a wakeup sequence.
At least on my Zotac CI321 the BIOS resets the wakeup sequence at each boot
to a factory default. Therefore I use a udev rule
SUBSYSTEM=="rc", DRIVERS=="nuvoton-cir", ACTION=="add", RUN+="<script>"
with the script basically doing
cat <stored wakeup sequence> >/sys${DEVPATH}/wakeup_data

IS_ERR_VALUE() assumes that its parameter is an unsigned long.
It can not be used to check if an unsigned int reflects an error.

The device initialization completes only after calling
input_register_device(). However, rc_open() can be called while
the device is being registered by the input/evdev core. So, we
can't expect that rc_dev->initialized to be true.
Change the logic to don't require initialized == true at rc_open
and change the type of initialized to be atomic.
this way, we can check for it earlier where it is really needed,
without needing to lock the mutex just for testing it.
Tested with nuvoton_cir driver on a NUC5i7RYB with CIR integrated on it.

While there's no risk of divison by zero, the logic there is akward, as it

calculating the numerator/denominator if not.

On my bttv card "Hauppauge WinTV [card=10]" capturing in YV12 fmt at max
size results in a solid green rectangle being captured (all colors 0 in
YUV).
This turns out to be caused by max-width (924) not being a multiple of 16.
We've likely never hit this problem before since normally xawtv / tvtime,
etc. will prefer packed pixel formats. But when using a video card which
is using xf86-video-modesetting + glamor, only planar XVideo fmts are
available, and xawtv will chose a matching capture format to avoid needing
to do conversion, triggering the solid green window problem.
