sh: support SIU sourcing from external clock on sh7722

Implement .set_rate() for all SH "div4 clocks," .enable(), .disable(), and
.set_parent() for those, that support them. This allows, among other uses,
reparenting of SIU clocks to the external source, and enabling and
disabling of the IrDA clock on sh7722.
