Add support to disable specific usb2 host ports, it's useful when a usb2 port is disabled on some platforms, but enabled on others for the same SoC, another case is that the different package may support different number of ports.
Signed-off-by: Chunfeng Yun <chunfeng.yun@mediatek.com> --- Due to there is property 'mediatek,u3p-dis-msk', prefer to use a similar name for the similar opertions, not spell out 'mask' as suggested by Rob.
