bus: ti-sysc: Fix missing reset delay handling
We have dts property for "ti,sysc-delay-us", and we're using it, but the
wait after OCP softreset only happens if devices are probed in legacy mode.
Let's add a delay after writing the OCP softreset when specified.
Fixes: e0db94fe87da ("bus: ti-sysc: Make OCP reset work for sysstatus and sysconfig reset bits")
