i2c: omap: Restore i2c context always
Currently the restore is done based on the flag OMAP_I2C_FLAG_RESET_REGS_POSTIDLE. This helps the following - The driver is always capable of restoring regardless of the off mode support being there or not. - While testing omap2430 it is found that in case of certain error paths (timeout) a reset is done. However the restore never happens as it is dependent on the POSTIDLE flag. The other option would be to call a restore in the reset case. As there are only a few registers to be restored the penalty in the idle case should not be much.
