OMAP2+: powerdomain: add API to get context loss count
Add new powerdomain API u32 pwrdm_get_context_loss_count(struct powerdomain *pwrdm) for checking how many times the powerdomain has lost context. The loss count is the sum of the powerdomain off-mode counter, the logic off counter and the per-bank memory off counter.
