rS357370: prci: fix up compat

Summary

Add two additional compat strings that can be used to identify the PRCI.

With newer device trees the PRCI has two parents, hfclk and rtcclk, so
allow the driver to attach when more than one parent is found.

Test Plan

Driver attaches with newer device tree, aka the one generated by QEMU.

I'm inferring that this driver was written using this device tree, as this is what is passed by the FSBL. If there is a different one that was used please point me to it.

Close to that, this is the BBL dump: http://people.freebsd.org/~kp/sifive_fu540.dts

It only lists "sifive,aloeprci0" for the PRCI, and only has a single parent clock.
