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 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. And since U-boot doesn't support ISOC,
we don't have to worry about 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 v5:
- Split up EHCI changeset
- usb_hub: replace the Faraday EHCI ifdef for the long delay
in usb_hub_configure() with the new configuration option:
USB_HUB_MIN_POWER_ON_DELAY, which is used in usb_hub_power_on()
to control the minimum usb hub power-on delay.
- ehci-faraday: fix the invalid multi-line comment style.
- gadget-fotg210: coding style cleanup.
- gadget-fotg210: drop postfix '__iomem' from struct fotg210_regs
- gadget-fotg210: use permanent delay for hardware reset
- gadget-fotg210: drop '#ifndef CONFIG_SYS_DCACHE_OFF'
- gadget-fotg210: drop magic numbers

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.

Kuo-Jung Su (4):
usb: make usb hub minimum power-on delay configurable
usb: add weak-aliased functions EHCI portsc & tdi routines
usb: ehci: add Faraday USB 2.0 EHCI support
usb: gadget: add Faraday FOTG210 USB gadget support
