Subject: [PATCH 6/8] phy: renesas: rcar-gen3-usb2: change a condition "dr_mode"

This patch changes a condition about dr_mode. If a device node has
any dr_mode ("host", "peripheral" or "otg"), this driver allows to
set "is_otg_channel" to true. Also, this patch keeps the dr_mode
value for future use.
