After a softreset, make sure the sysc settings are correctly
restored.

omap_hwmod_softreset() does not seem to wait for reset status
after doing a softreset. Make it use _ocp_softreset() instead
which does this correctly.

Could you base this on either my 'hwmod_code_cleanup_3.4' branch or
'hwmod_enable_remaining_hwmods_devel_3.4' branch? There are some reset
changes in there also.
