Add new HCIUART protocol HCIUART_IBS which enables the Bluetooth
device to enter a low power state when possible. It also tells
the msm_serial_hs UART driver that it may go to a low-power state
even though the port is open.

This change removes source files from the kernel tree that
were not being used during make. The list of used files
was generated using an annotated make log and was then
compared with new files added since the public release of
kernel version 3.10.00. New files which were added but
not used have been removed from the tree.
A diff was also run to determine the list of files that had
been modified since the release of kernel version 3.10.00.
These files were then scrubbed based on the current kernel
configuration, removing invalid and unused conditionals.
Some files which support planned functionality or are
useful in debugging have been excluded from this reap.

The option allows you to remove TTY and compile without errors. This
saves space on systems that won't support TTY interfaces anyway.
bloat-o-meter output is below.
The bulk of this patch consists of Kconfig changes adding "depends on
TTY" to various serial devices and similar drivers that require the TTY
layer. Ideally, these dependencies would occur on a common intermediate
symbol such as SERIO, but most drivers "select SERIO" rather than
"depends on SERIO", and "select" does not respect dependencies.
bloat-o-meter output comparing our previous minimal to new minimal by
removing TTY. The list is filtered to not show removed entries with awk
'$3 != "-"' as the list was very long.

This is the bluetooth protocol driver for the TI WiLink7 chipsets.
Texas Instrument's WiLink chipsets combine wireless technologies
like BT, FM, GPS and WLAN onto a single chip.
This Bluetooth driver works on top of the TI_ST shared transport
line discipline driver which also allows other drivers like
FM V4L2 and GPS character driver to make use of the same UART interface.
Kconfig and Makefile modifications to enable the Bluetooth
driver for Texas Instrument's WiLink 7 chipset.

The Marvell driver selects DEBUG_FS and FW_LOADER for its core driver
and that is pointless. Don't select DEBUG_FS since it is either enabled
or not and it is not for the driver to enable it. Also FW_LOADER is
only used within the SDIO driver and so just have that one select the
FW_LOADER option.

The old hci_usb driver has been fully replaced with the new btusb driver
and all major distributions switched to the new driver now. This removes
it since it should not be used at all anymore.

The new generic driver for Bluetooth USB devices was missing proper
SCO support. The driver now claims the second interface for these USB
devices to allow the flow of SCO packets. It also handles switching
of the alternate setting and re-submission of isochronous URBs.
The btusb driver is now a full replacement for hci_usb and thus the
experimental tag has been removed and this driver is promoted as
preferred one.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
