[PATCH v2 2/2] usb: host: ehci-platform: add ignore_oc DT support

[Álvaro Fernández Rojas]

Over-current reporting isn't supported on some platforms such as bcm63xx.
These devices will incorrectly report over-current if this flag isn't properly
activated.

Signed-off-by: Álvaro Fernández Rojas <noltari@xxxxxxxxx>

 v2: change flag name and improve documentation as suggested by Alan Stern.
