net: dsa: lan9303: fix reset on probe
commit 6bb9681a43f34f2cab4aad6e2a02da4ce54d13c5 upstream.
The reset input to the LAN9303 chip is active low, and devicetree
gpio handles reflect this. Therefore, the gpio should be requested
with an initial state of high in order for the reset signal to be
asserted. Other uses of the gpio already use the correct polarity.
