From: Santosh Shilimkar <santosh.shilim...@ti.com>
Context register in various power domain is not at same offset
on OMAP4. Mainly the CPUx context resgiters againts rest of
them. This patch adds a field in power-domain strucures to handle
this.
This will be needed to make "pwrdm_clear_all_prev_pwrst" API work on
OMAP4.
