Restore of context is not done for OMAP4. This patch
adds the OMAP_I2C_FLAG_RESET_REGS_POSTIDLE in the OMAP4
hwmod data which activates the restore for OMAP4.
Currently the OMAP4 does not hit device off still the
driver may have support for it.

Subject should include 'hwmod data', and fix up the spacing:
OMAP4: hwmod data: I2C: add flag for context restore
