[PATCH 4.19 093/115] arm64: dts: meson: odroid-c2: Disable usb_otg bus to avoid power failed warning

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

From: Anand Moon <linux.amoon@gmail.com>

commit 72c9b5f6f75fbc6c47e0a2d02bc3838a2a47c90a upstream.

usb_otg bus needs to get initialize from the u-boot to be configured
to used as power source to SBC or usb otg port will get configured
as host device. Right now this support is missing in the u-boot and
phy driver so to avoid power failed warning, we would disable this
feature  until proper fix is found.
