Sagar Kadam 406171bf9a dt-bindings: fu540: prci: convert PRCI bindings to json-schema
FU540-C000 SoC from SiFive has a PRCI block, here we convert
the device tree bindings from txt to YAML.

description:
On the FU540 family of SoCs, most system-wide clock and reset integration
is via the PRCI IP block.
The clock consumer should specify the desired clock via the clock ID
macros defined in include/dt-bindings/clock/sifive-fu540-prci.h.
These macros begin with PRCI_CLK_.
The hfclk and rtcclk nodes are required, and represent physical
crystals or resonators located on the PCB. These nodes should be present
underneath /, rather than /soc.
