[PATCH v1] dt-bindings: i2c: microchip,corei2c: permit resets

[Conor Dooley <conor@kernel.org>]

From: Conor Dooley <conor.dooley@microchip.com>

Both CoreI2C and the hardened versions of it on mpfs and pic64gx have a
reset pin. For the former, usually this is wired to a common fabric
reset not managed by software and for the latter two the platform
firmware takes them 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.
