set-right the error codes that the shared transport driver
returns.
Instead of magic numbers like -1, return relevant codes such as
ETIMEDOUT or EIO, EAGAIN when wait times out or uart write bytes don't
match expected value or when registration fails and needs to be
attempted again.

The architecture of shared transport had begun with individual
protocols like bluetooth, fm and gps telling the shared transport
what sort of protocol they are and then expecting the ST driver
to parse the incoming data from chip and forward data only
relevant to the protocol drivers.
This change would mean each protocol drivers would also send
information to ST driver as to how to intrepret their protocol
data coming out of the chip.

Based on comments from Jiri Slaby, drop the register
storage specifier, remove the unused code, cleanup
the const to non-const type casting.
Also make the line discipline ops structure static, since
its a singleton, unmodified structure which need not be
in heap.

move the 3 source files st_core.c, st_kim.c and st_ll.c
from staging to drivers/misc/.
Texas Instrument's WiLink 7 chipset packs wireless technologies like
Bluetooth, FM, GPS and WLAN into a single die.
Among these the Bluetooth, FM Rx/Tx and GPS are interfaced to a apps processor
over a single UART.
This line discipline driver allows various protocol drivers such as Bluetooth
BlueZ driver, FM V4L2 driver and GPS simple character device driver
to communicate with its relevant core in the chip.
Each protocol or technologies use a logical channel to communicate with chip.
Bluetooth uses the HCI-H4 [channels 1-4], FM uses a CH-8 and
GPS a CH-9 protocol. The driver also constitutes the TI HCI-LL Power
Management protocol which use channels 30-33.
