usb: ehci: add Faraday USB 2.0 EHCI support
This patch adds support to both Faraday FUSBH200 and FOTG210, the differences between Faraday EHCI and standard EHCI are listed bellow: 1. The PORTSC starts at 0x30 instead of 0x44. 2. The CONFIGFLAG(0x40) is not only un-implemented, and also has its address space removed. 3. Faraday EHCI is a TDI design, but it doesn't compatible with the general TDI implementation found at both U-Boot and Linux. 4. The ISOC descriptors differ from standard EHCI in several ways. But since U-boot doesn't support ISOC, we don't have to worry about that. Signed-off-by: Kuo-Jung Su <dantesu@faraday-tech.com> CC: Marek Vasut <marex@denx.de>
