Move CONFIG_USB_XHCI to defconfig files for all boards, renaming it
into CONFIG_USB_XHCI_HCD.

As commented in the help of "config USB_XHCI" entry, this has been
a TODO for a long time; now CONFIG_USB_XHCI_HCD and CONFIG_USB_XHCI
have been unified in favor of the former.

Note:
Some boards define CONFIG_USB_XHCI in their headers without
CONFIG_USB, which does not meet the "depends on" in Kconfig.
I added CONFIG_USB=y for those boards when converting.
Otherwise, they would fail to build.

This driver is able to reconfigure OTG controller into HOST mode.
Board can add board-specific initialization as board_prepare_usb().
It requires USB_ULPI_VIEWPORT enabled in board configuration.

Now, all this driver does can be covered by the generic EHCI driver
(drivers/usb/host/ehci-generic.c).  UniPhier SoCs have switched to
use it.  Delete this driver rather than bothering to convert it to
Driver Model.

This driver is meant to be used with any OHCI-compatible host
controller in case if there's no need for platform-specific
glue such as setup of controller or PHY's power mode via
GPIOs etc.
