usb: Fix bootindex for portnr > 9

We identify devices by their Open Firmware device paths.  The encoding
of the host controller and hub port numbers is incorrect:
usb_get_fw_dev_path() formats them in decimal, while SeaBIOS uses
hexadecimal.  When some port number > 9, SeaBIOS will miss the
bootindex (lucky case), or apply it to another device (unlucky case).

The relevant spec[*] agrees with SeaBIOS (and OVMF, for that matter).
Change %d to %x.

Bug can bite only with host controllers or hubs sporting more than ten
ports.  I'm not aware of any.

Fix OHCI ISO TD state never being written back.

There appears to be typo in OHCI with isochronous transfers
resulting in isoch. transfer descriptor state never being written back.
The'put_words' function is in a OR statement hence it is never called.

Revert "xhci: Fix number of streams allocated when using streams"

This reverts commit d063c3112c4cd23a479ee18720c2bd119da2d315.

"2 << x" is the same as "2 ^ (x + 1)", so the old code is correct.

target-arm: Fix regression that disabled VFP for ARMv5 CPUs

Commit 2c7ffc414 added support for honouring the CPACR coprocessor
access control register bits which may disable access to VFP
and Neon instructions. However it failed to account for the
fact that the CPACR is only present starting from the ARMv6
architecture version, so it accidentally disabled VFP completely
for ARMv5 CPUs like the ARM926. Linux would detect this as
"no VFP present" and probably fall back to its own emulation,
but other guest OSes might crash or misbehave.

This fixes bug LP:1359930.
