Patches for Freescale MXC SoCs and direct ULPI communication [v3]

[Daniel Mack]

Sorry for the long delay on this issue.

Here comes another round of four patches to support the EHCI ports on
Freescale's MX2/MX3 SoCs.

The difference to the last version I've sent is that the ISP1504
specific drivers has become a generic ULPI driver now with all the
defines renamed.

Also the driver does not set DRV_VBUS and DRV_VBUS_EXT blindly
anymore but uses a flags field in the otg_transceiver struct which can
be specified when creating the device. This allows the adaption of the
code to a wider variety of applications.

As a reference, I've added a patch to add board specific support code
for the lilly1131 module.

Let me know if that still works for other boards and if that version
looks better to you.

Again, #1, #2 and #4 are supposed to go thru the USB folks' channel,
while the rest might be picked by Sascha Hauer eventually.

Thanks,
Daniel
