[PATCH 4.4 055/132] ARM: dts: at91: sama5d4_xplained: add pincontrol for USB Host

[Greg Kroah-Hartman]

From: Cristian Birsan <cristian.birsan@xxxxxxxxxxxxx>

[ Upstream commit be4dd2d448816a27c1446f8f37fce375daf64148 ]

The pincontrol node is needed for USB Host since Linux v5.7-rc1. Without
it the driver probes but VBus is not powered because of wrong pincontrol
configuration.
