OMAP2/3: hwmod: fix gpio-reset timeouts seen during bootup.

GPIO module expects the debounce clocks to be enabled during reset. It doesn't
reset properly and timeouts are seen, if this clock isn't enabled during
reset. Add the HWMOD_CONTROL_OPT_CLKS_IN_RESET flags to the GPIO HWMODs, with
which the debounce clocks are enabled during reset.
