[PATCH 3/5 v4] USB: enclose EHCI HCD drivers within an if USB_EHCI_HCD block

[Florian Fainelli]

Thist patch removes the depends on USB_EHCI_HCD that the various USB
EHCI HCD drivers use and encloses every driver within an if USB_EHCI_HCD
/ endif block. The EHCI HCD platform and Octeon drivers have been moved
around to remain enclosed within this block.

Changes in v4:
- added Alan's Acked-by tag
- refreshed against latest usb-next

Changes in v3:
- move out USB_FSL_MPH_DR_OF from the USB_EHCI_HCD block
- remove depends on USB_EHCI_HCD for USB_EHCI_BIG_ENDIAN_DESC
