dt-bindings: clock: si544: add si549 compatible

Adding Si549 compatible, which uses different internal oscillator
frequency. Like in Si544 case, there are three types ending with
latters a,b and c. Each with different maximum output frequency.

Also fix datasheet links after Silicon Labs acquisition by
Skyworks Solutions.
