[PATCH v1] dt-bindings: usb: mpfs-musb: permit resets

[Conor Dooley]

From: Conor Dooley <conor.dooley@xxxxxxxxxxxxx>

The musb IP on mpfs and pic64gx has a reset pin, but until now this has
been undocumented because platform firmware takes the block out of reset
on first-party boards (or those using modified versions of the vendor
firmware), but not all boards may take this approach. Permit providing a
reset in devicetree for Linux, or other devicetree-consuming software,
to use.
