[PATCH 11/19] usb: ehci-mx6: Split ehci_mx6_common_init()

[Marek Vasut]

In order to pass component addresses around easily instead of passing
ad-hoc sequence numbers, it is necessary to split ehci_mx6_common_init().
Make it so and call the separate functions instead.

Since board_ehci_hcd_init() makes no sense in DM case, do not call it
in DM case.

Fixes: 4de51cc25b5 ("usb: ehci-mx6: Drop assignment of sequence number")
