USB Debug Port related license header fixes (trivial). - Add missing license headers, or missing (C) lines to various files. (most are from AMD / Yinghai Lu, based on svn logs) - src/include/ehci.h was taken from the Linux kernel. Updating it to the latest version from git HEAD while I'm at it (build-tested with one board). It also sports some new EHCI 1.1 addendum #defines which we may or may not need. This new file also already has a proper GPL header.

This is (most of) the usb2 debug console code ripped out of Uwe's version of yh_rest_of_patch.patch (13.02.07 - [PATCH] Rest of huge MCP55 patch). I dropped a lot of stuff, like broken indenting, removed copyright messages, and this printk_ram_* stuff (what the heck is this supposed to be) This codebase is really a mess. Further tarball contributions without a _CLEANED UP_ patch will be denied, especially if they are not from an up to date svn tree.

usbdebug: Drop duplicates of EHCI BAR relocation code All the additional work that needs to be done in EHCI BAR relocation is independent of the hardware platform and was functionally identical in all the copies removed. When USBDEBUG is not selected, PCI EHCI controllers use standard pci_dev_read_resources() call. With USBDEBUG selected, PCI EHCI controller's device_operations .read_resources is replaced with pci_ehci_read_resources() call, which in turn will replace the device_operations .set_resources call. The replacement for .set_resources reconfigures usbdebug driver side, and calls the original .set_resources to configure hardware side.
