Subject: [PATCH 1/2] gpio: mcp23s08: rename the device tree property

From: Lars Poeschel <poeschel@...onage.de>

The device tree property should be more descriptive.
microchip seems more reasonable than mcp. As there are no
in tree users of this property, so the rename can still be
done without pain.
