It is possible to specify a device tree node for an USB device. This is
useful if you have a static USB setup and want to use aliases which
point to these nodes, like on the Raspberry Pi.
The nodes are matched against their hub port number, the compatible
strings are not matched for now.

Allow the unit test to pass full 8 byte scan code sequences to the USB
keyboard emulation driver and to parse multi-byte escape sequences.
The following features are not yet tested:
* LED status
* caps-lock
* num-lock
* numerical pad keys
The following features are not yet implemented by the USB keyboard
driver and therefore not tested:
* modifiers for non-alpha-numeric keys, e.g. <SHIFT><TAB> and <ALT><F4>
* some special keys, e.g. <PRINT>
* some modifiers, e.g. <ALT> and <META>
* alternative keyboard layouts

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.

Now that we have changed to remove all devices under the root hub in
usb_stop(), and corrected the USB emulator select logic, it makes no
sense to do various tests based on 'usb tree' output since the order
of devices is no longer fixed. Remove these USB test cases related
to 'usb tree'.
For the USB remove test, ideally we should remove an emulator device
node from the device tree, but this is so far not working. Change to
test the 'usb stop' only.

The USB subsystem has a few counters that need to be reset since they are
stored in static variables rather than driver-model data. An example is
usb_max_devs. Ultimately we should move this data into the USB uclass.
For now, make sure that USB is reset after each test, so that the counters
go back to zero.
Note: this is not a perfect solution: It a USB test fails it will exit
immediately and leave USB un-reset. The impact here is that it may cause
subsequence test failures in the same run.

To ease conversion to driver model, add helper functions which deal with
calling each block device method. With driver model we can reimplement these
functions with the same arguments.
Use inline functions to avoid increasing code size on some boards.

Use 'struct' instead of a typdef. Also since 'struct block_dev_desc' is long

This will allow the implementation to make use of data in the block_dev
structure beyond the base device number. This will be useful so that eMMC
block devices can encompass the HW partition ID rather than treating this
out-of-band. Equally, the existence of the priv field is crying out for
this patch to exist.
