OMAP: hwmod: Disable clocks when hwmod enable fails
In cases where a module(hwmod) does not become accesible on enabling
the main clocks (can happen if there are external clocks needed
for the module to become accesible), make sure the clocks are not
left enabled.
This ensures that when the requisite external depenedencies are met
a omap_hwmod_enable and omap_hwmod_idle/shutdown would rightly enable
and disable clocks using clk framework. Leaving the clocks enabled in
the error case causes additional usecounting at the clock framework
level leaving the clock enabled forever.
