[U-Boot] [PATCH] ARM: rpi: enable USB keyboard

[Stephen Warren]

Now that the DWC2 driver supports split transactions, we can reasonably
enable support for USB keyboards. This wasn't terribly useful before
since keyboards are usually LS/FS devices, and thus require split
transaction support when attached to a USB hub such as the hub built into
the RPi model Bs.

This depends on Stefan Brüns' series "usb: dwc2: add SPLIT transaction
support".
