apm821xx: add amcc, usb-otg-405ex devicetree definition
This patch adds support for the amcc,usb-otg-405ex device which is found in all APM82181 SoCs. Note: The system can't use the generic "snps,dwc2" compatible because of the special ahbcfg configuration. The default GAHBCFG_HBSTLEN_INCR4 of snps,dwc2 can cause a system hang when the USB and SATA is used concurrently. Signed-off-by: Christian Lamparter <chunkeey@gmail.com>
