Subject: [PATCH] phy: tegra: xusb: Release device node reference

Platform device reference is retrieved using the device node using a call
to of_find_device_by_node(). Since we do not need to maintain the device
node reference further, we can release it back to the core.

Signed-off-by: Deepak R Varma <drv@...lo.com>

Please note: The patch proposal is compile tested using tegra defconfig.
