From: Kuo-Jung Su <dantesu at faraday-tech.com>

This patch add supports to both Faraday FUSBH200 and FOTG210,
the differences between Faraday EHCI and standard EHCI as
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 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 differs from standard EHCI in
   several ways. Since U-boot doesn't support ISOC,
   we don't have to worry that.

The Faraday FOTG210 is an OTG chip which could operate
as either an EHCI Host or a USB Device as a time.

Changes for v4:
   - Use only macro constants and named bit/mask
   - Use weak-aliased functions for tdi implementation and
     also portsc registers to avoid poluting ehci.h with ifdefs

Changes for v3:
   - Coding Style cleanup.
   - Drop bit fields from c struct.
   - Drop macros for wirtel()/readl(), call them directly.
   - Always insert a blank line between declarations and code.
   - Replace all the infinite wait loop with a timeout.
   - Add '__iomem' to all the declaration of HW register pointers.

Changes for v2:
   - Coding Style cleanup.
   - Use readl(), writel(), clrsetbits_le32() to replace REG() macros.
   - Use structure based hardware registers to replace the macro constants.
   - Replace BIT() with BIT_MASK().
   - echi-faraday: Remove debug codes.
