bus: ti-sysc: Use optional clocks on for enable and wait for softreset bit



Some modules reset automatically when idled, and when re-enabled, we must
wait for the automatic OCP softreset to complete. And if optional clocks
are configured, we need to keep the clocks on while waiting for the reset
to complete.

Let's fix the issue by moving the OCP softreset code to a separate
function sysc_wait_softreset(), and call it also from sysc_enable_module()
with the optional clocks enabled.

This is based on what we're already doing for legacy platform data booting
in _enable_sysc().
