ARM: dts: imx6q-logicpd: Reduce inrush current on USBH1
commit 7aedca875074b33795bc77066b325898b1eb8032 upstream.
Some USB peripherals draw more power, and the sourcing regulator
take a little time to turn on. This patch fixes an issue where
some devices occasionally do not get detected, because the power
isn't quite ready when communication starts, so we add a bit
of a delay.
