Subject: [PATCH] arm64: tegra: Make BCM89610 PHY interrupt as active low

[ Upstream commit 9df50ba76ac1485b844beffa1f3f5d9659d9cdaf ]

Need to configure PHY interrupt as active low for P3310 Tegra186
platform otherwise it results in spurious interrupts.

This issue wasn't seen before because the generic PHY driver without
interrupt support was used.
