OMAP: PM noop: implement context loss count for non-omap_devices
For devices which have not (yet) been converted to use omap_device,
implement the context loss counter using the "brutal method" as
originally proposed by Paul Walmsley[1].
The dummy context loss counter is incremented every time it is
checked, but only when off-mode is enabled. When off-mode is
disabled, the dummy counter stops incrementing.
Tested on 36xx/Zoom3 using MMC driver, which is currently the
only in-tree user of this API.
This patch should be reverted after all devices are converted to using
omap_device.
