Suspend/resume can be very tricky. That's the second attempt to fix
it with au0828.
With this patchset, suspend/resume to ram works fine if the device
is not being used. After resume, IR, digital TV and analog TV
keeps working.
On my tests, however, trying to suspend while watching TV caused
my test machine to crash. I suspect, however, that the bug could
be at the USB driver level.
Anyway, before this series, the device even didn't suspend, so
it is clearly a progress.
Tested on an Odroid-U3 running Tizen with a very light stack. I'll
test this also on some x86_64 hardware.
