OMAP: hwmod: Fix softreset for modules with optional clocks
Some modules (like GPIO, DSS...) require optionals clock to be enabled in order to complete the sofreset properly. Add a HWMOD_CONTROL_OPT_CLKS_IN_RESET flag to force all optional clocks to be enabled before reset. Disabled them once the reset is done. TODO: For the moment it is very hard to understand from the HW spec, which optional clock is needed and which one is not. So the current approach will enable all the optional clocks. Paul proposed a much finer approach that will allow to tag only the needed clock in the optional clock table. This might be doable as soon as we have a clear understanding of these dependencies.
