ARM: DRA7/OMAP5: EMIF: Add workaround for bug 0039
When core power domain hits oswr, then DDR3 memories does not come back while resuming. This is because when EMIF registers are lost, then the controller takes care of copying the values from the shadow registers. If the shadow registers are not updated with the right values, then this results in incorrect settings while resuming. So updating the shadow registers with the corresponding status registers here during the boot. Signed-off-by: Sricharan R <r.sricharan@ti.com>
