7bb4f86d07 usbdebug: Refactor on EHCI memory space
We only reference with ehci_caps and ehci_regs during initialisation,
no need to carry those around.

When EHCI BAR is relocated during PCI allocation, record the changed
address even if usbdebug is not enabled. Use the DBGP_EP_VALID flags
to determine if endpoints have been configured or not.

618d179bfe usbdebug: Fix migration to ramstage
On entry to ramstage CBMEM is looked for a copy of an already initialized
EHCI debug dongle state. If a copy is found, it contained the state before
CAR migration and the USB protocol data toggle can be out of sync. It's an
even/odd kind of a parity check, so roughly every other build would
show the problem as invalid first line: 'ug found in CBMEM.'

After CAR migration, re-direct the state changes to correct CBMEM table.

cb141bce35 usbdebug: Split PCI EHCI part
There are EHCI compatible host controllers on ARM without PCI bus
architecture. Currently we have not come across one with the debug
capability though.

48e899d2d5 usbdebug: Fix data toggle on receive
USB device end toggles data PID when we ACK'd the zero-length data
packet. As USB host we need to toggle data PID too or the next data
received would get discarded.
