5774a864b1 usb_drv: Fix PHY initialization for DWC3 XHCI
Make high speed (HS) and super speed (SS) hub use the same reference clock.
Also upgrade some quotas in USB run scripts.

Fixes #929.

33305dd08d Fix usb_storage.run for non-PC platforms
On non-PC platforms, the variable 'build' remains undefined, which lets
the 'build $build' step fail. Use the traditional 'build_components'
variable instead. As a further plus, this avoids multiple passes of the
build system.

cda25a481b usb: Make host controller types configurable
The host controller type (u/e/xhci) usded by the drivers can be configured
through attributes of the config node. See: README

3207b4eed0 USB: Performance improvements
Added SKB bitmap allocator, use Nic::Packet_allocator in packet stream, use slab
allocators on top of back-end AVL allocator, split allocators in cached/uncached
for general purpose/DMA allocation, added patch to original code to distinguish
cached or uncached memory requests, take advantage of and implement TX bursts
(or SKB batching), call interrupt handlers until they return unhandled.

e1435a3f57 Replace old test/block with test/ahci
The block test at test/ahci is indeed not AHCI-specific. It is a generic
block read/write test for the block-session interface. But in contrast
to the original test/block, it restores the block device content (at
least when the test succeeds). Hence, we remove the original (dangerous)
block test and always use code of test/ahci.

9f73476b37 New DDE-Linux-based USB driver
The new 'dde_linux' repository will host device drivers ported from the
Linux kernel. In contrast to the original 'linux_drivers' repository,
'dde_linux' does not contain any 3rd-party source code. To download the
Linux kernel source code and extract the drivers, execute the 'make
prepare' rule of the top-level Makefile. The initial version of the
'dde_linux' repository comes with an USB driver. The porting methodology
follows the path of the Intel GEM port. Instead of attempting to provide
a generic Linux environment that works across drivers, each driver comes
with a specially tailored DDE.

The DDE consists of Genode-specific implementations of Linux API
functions as declared in 'lx_emul.h'. Most of these functions are
dummies that must merely be provided to resolve dependencies at the
linking stage. They are called by unused code-paths.

As of now, the USB driver support UHCI, EHCI on the x86_32 platform. I
exposes USB HID devices and USB storage devices via Genode's input-session
and block-session respectively.

The USB driver is accompanied with two run scripts 'run/usb_hid.run' and
'run/usb_storage.run'.
