libusbdrivers: Minor fix.

libusbdrivers: Use ps_malloc_ops;

libusbdrivers: Use delay function from libplatsupport.

libusbdrivers: Remove duplicated aborts.

libusbdriver: USB data type rework.

libusbdrivers: Minor fixes.

libusbdrivers: Move various functions to other libraries.

libusbdrivers: Move synchronization structure to libplatsupport.

libusbdrivers: Add licence headers.

libusbdrivers: Minor fixes.

libusbdrivers: Check memory allocation.

libusbdrivers: Replace all assertions and debug macros with ZF_LOG.

libusbdrivers: Cleanup code.

libusbdrivers: Added HID class driver.

libusbdrivers: Add TT address and port to support low/full speed hub.

libusbdrivers: Some devices require a pause during initialization. And it is
optional for the device driver to parse descriptors.

libusbdrivers: Use less ambiguous locking interface.

libusbdrivers: Reset the port if the device is unplugged in the enumeration
process.

libusbdrivers: Remove inactive device list, as it is never being used.

libusbdrivers: When disconnecting a Hub, disconnect all devices that connect to
it recursively.

libusbdrivers: Remove queue head for async schedule.

libusbdrivers: Added mutex functions to the APIs.

libusbdrvier: Define the bmRequestType bitmap.

libusbdrivers: Fix typos.

libusbdrivers: Bugfix where the descriptor parser enter infinite loop when
the device report incorrent descriptor size.

libusbdrivers: Handle control transfer with no data stage in the EHCI driver.

libusbdrivers: Move print string descriptor to USB core.

libusbdrivers: Change APIs, introduce the endpoint structure.

libusbdrivers: Add data toggle to the USB scheduling API.

libusbdrivers: Get device string based on language ID.

Fix licenses

libusbdrivers: Fix bugs in devlist_insert function in usb.c

The while loop had an incorrect check that resulted in an infinite loop
and the next_addr variable was never getting incremented when a new device
was added to the list

libusbdrivers: Add 0 length data packets to configuration stage of devices

The Sabre lite was unhappy without these because it seems to need them in
order to distinguish an end of transfer and would error when initialising
devices.
