ARM: OMAP2+: hwmod: add parent_hwmod support
Add parent_hwmod pointer to omap_hwmod. This can be set to point to a "parent" hwmod that needs to be enabled for the "child" hwmod to work. This is used at hwmod setup time: when doing the initial setup and reset, first enable the parent hwmod, and after setup and reset is done, restore the parent hwmod to postsetup_state.
