Tom Rini be5c0608b8 usb: Enforce DM_USB migration for USB_HOST devices.
As the deadline for migration to DM_USB, when using a USB host
controller has now gone two years past the deadline, enforce migration.
This is done by:

- Ensuring that all host controller options (other than the very legacy
  old MUSB ones) now select USB_HOST.  USB_HOST now enforces DM_USB and
  OF_CONTROL.
  - Remove other parts of Kconfig logic that had platforms pick DM_USB.
  - To keep Kconfig happy, have some select statements test for USB_HOST
    as well.
- Re-order some Kconfig entries and menus so that we can cleanly pick
  host or gadget roles.  For the various HCD options that have platform
  glue options, group them together and update dependencies in some
  cases.
- As SPL_DM_USB is not required, on platforms that had not yet enabled
  it, disable it.

menuconfig USB
bool "USB support"
---help---
Universal Serial Bus (USB) is a specification for a serial bus
subsystem which offers higher speeds and more features than the
traditional PC serial port. The bus supplies power to peripherals
and allows for hot swapping. Up to 127 USB peripherals can be
connected to a single USB host in a tree structure.
The USB host is the root of the tree, the peripherals are the
leaves and the inner nodes are special USB devices called hubs.
Most PCs now have USB host ports, used to connect peripherals
such as scanners, keyboards, mice, modems, cameras, disks,
flash memory, network links, and printers to the PC.
Say Y here if your device has an USB port, either host, peripheral or
dual-role.
For an USB host port, you then need to say Y to at least one of the
Host Controller Driver (HCD) options below. Choose a USB 1.1
controller, such as "UHCI HCD support" or "OHCI HCD support",
and "EHCI HCD (USB 2.0) support" except for older systems that
do not have USB 2.0 support. It doesn't normally hurt to select
them all if you are not certain.
If your system has a device-side USB port, used in the peripheral
side of the USB protocol, see the "USB Gadget" framework instead.
After choosing your HCD, then select drivers for the USB peripherals
you'll be using. You may want to check out the information provided
in <file:Documentation/usb/> and especially the links given in
<file:Documentation/usb/usb-help.txt>.

Enable driver model for USB. The USB interface is then implemented
by the USB uclass. Multiple USB controllers of different types
(XHCI, EHCI, OHCI) can be attached and used. The 'usb' command works
as normal.
Much of the code is shared but with this option enabled the USB
uclass takes care of device enumeration. USB devices can be
declared with the U_BOOT_USB_DEVICE() macro and will be
automatically probed when found on the bus.
