[PATCH v2 0/6] ARM: mx28: add usb host function

[Tony Lin]

this patch series is to add mx28 usb host function.
the driver only support usb host mode on usb port1.
the driver reuses ehci-mxc.c under usb/host, but did
some modifications based on it to satisfy mx28 usb host
requirement. The modifications will not affect other
platforms.

Code is based on the branch for-next in sascha's tree http://git.pengutronix.de/git/imx/linux-2.6.git

Tested on MX28 EVK.

changes since v1:
 * add dummy clock to avoid adding cpu judgement in driver for Sascha's request.
 * use context in phy functions, so that usb device could share the code.
 * some code consolidation and patch reorgnization.
 * error checking improvement.
 * remove a few unneccesary code.
