bcbe3d1579 dm: Rename dev_get_parentdata() to dev_get_parent_priv()
The current name is inconsistent with other driver model data access
functions. Rename it and fix up all users.

779d126391 dm: usb: xhci: Factor out common init/uninit
Since driver model will want to use most of the same code for XHCI init
and uninit, put it in a separate function.

7c1deec0af dm: usb: xhci: Use a function to get xhci_ctrl
Rather than getting this directly from struct usb_device, call a function
to obtain it. This will make it possible for driver model to provide it
another way.

421a5a0c98 usb: 64-bit architectures support for xHCI
This commit allows xHCI to use both 64 and 32 bit memory
physical addresses depending on architecture it's being built for.
Also it makes use of readq()/writeq() on 64-bit systems

b41411954d linux/kernel.h: sync min, max, min3, max3 macros with Linux
U-Boot has never cared about the type when we get max/min of two
values, but Linux Kernel does.  This commit gets min, max, min3, max3
macros synced with the kernel introducing type checks.

Many of references of those macros must be fixed to suppress warnings.
We have two options:
 - Use min, max, min3, max3 only when the arguments have the same type
   (or add casts to the arguments)
 - Use min_t/max_t instead with the appropriate type for the first
   argument

25d1936a19 usb: xhci: (likely) fix bracket in if condition
Because of the brackets the & and && is evaluated before
the comparison. This is likely not the intention. Change
it to test the first and second condition to both be true.

5853e1335c USB: xHCI: Add stack support for xHCI
This adds stack layer for eXtensible Host Controller Interface
which facilitates use of USB 3.0 in host mode.

Adapting xHCI host controller driver in linux-kernel
by Sarah Sharp to needs in u-boot.

Initial porting from Linux kernel version 3.4, with following
top commit history of drivers/usb/host/xhci* :
cf84055 xHCI: Cleanup isoc transfer ring when TD length mismatch found

This adds the basic xHCI host controller driver with bare minimum
features:
- Control/Bulk transfer support has been added with required
  infrastructure for necessary xHC data structures.
- Stream protocol hasn't been supported yet.
- No support for quirky devices has been added.
