FROMGIT: dt-bindings: can: microchip,mcp251xfd: allow gpio-hog child nodes

The MCP251XFD can expose two pins as GPIOs. The binding already declares
gpio-controller and #gpio-cells for the device. Whitelist GPIO hog child
nodes using patternProperties so boards can set default GPIO states at
boot via DT, consistent with other GPIO controllers
(e.g. microchip,mpfs-gpio).
