====================
net: dsa: microchip: Add strap description to set SPI as interface bus

At reset, the KSZ8463 uses a strap-based configuration to set SPI as
interface bus. If the required pull-ups/pull-downs are missing
(by mistake or by design to save power) the pins may float and the
configuration can go wrong preventing any communication with the switch.

This small series aims to allow to configure the KSZ8463 switch at
reset when the hardware straps are missing.

PATCH 0 and 1 add a new property to the bindings that describes the GPIOs
to be set during reset in order to configure the switch properly.

PATCH 2 implements the use of these properties in the driver.
