usb host: Faraday USB2.0 FUSBH200-HCD driver

FUSBH200-HCD is an USB2.0 hcd for Faraday FUSBH200.
FUSBH200 is an ehci-like controller with some differences.
First, register layout of FUSBH200 is incompatible with EHCI.
Furthermore, FUSBH200 is lack of siTDs which means iTDs
are used for both HS and FS ISO transfer.
