For future extension, change xhci_setup_addressable_virt_dev()
signature to accept a pointer to 'struct usb_device', instead
of its members slot_id & speed, as the struct already contains
these two plus some other useful information of the device.

The scratchpad buffer array is used to define the locations of
statically allocated memory pages that are available for the
private use of the xHC. The xHCI spec explicitly mentions that
system software shall allocate the scratchpad buffers before
placing the xHC in to Run mode (Run/Stop (R/S) = ‘1’), however
U-Boot is missing this part.
This causes xHC on Intel platform does not respond the very first
'enable slot' command that is given to xHC and the 'enable slot'
command completion event TRB is never generated and xHC seems to
hang forever.

Now, include/linux/errno.h is a wrapper of <asm-generic/errno.h>.
Replace all include directives for <asm-generic/errno.h> with
<linux/errno.h>.
<asm-generic/...> is supposed to be included from <asm/...> when
arch-headers fall back into generic implementation. Generally, they
should not be directly included from .c files.

This function should not be delving into struct usb_device. Pass in the
parameters it needs directly.

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

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.
