Older mechanism of counting the number of protocols
registered with ST was slow, in-efficient.
It used to check the protocol data for NULL for each
registration/unregistration.
With this change, counting protocols in maintained by
a single counter protos_registered.
Counting protocols is not just for debug purposes

Remove the older way of communicating with user-space
daemon UIM.
The older way involved creating of a new kobj and pid
sysfs file under it, and sending signal using that pid.
Now we communicate via rfkill to user-space UIM.
Background: UIM is the user-space daemon which upon
notification from ldisc driver, opens the tty, sets
default baud and then installs (tiocsetd) the ldisc.

Update the TODO of TI-ST to make sure it reflects current list
of activities that need to be done.
Also point it out to the user-space app code relevant to it.

Fix build errors. st_kim.c uses rfkill*() interfaces, so it
should depend on RFKILL.

Texas Instruments BT, FM and GPS combo chips/drivers

This is the common header file for both the ST driver and the

Kernel Space Init-Manager works along with User-Mode
Init Manager daemon running to maintain the UART state.
Communication between user-space daemon and this module can be
1. Via the pid written onto sysfs entry
2. Via the rfkill subsystem
It also is a platform driver with a relevant platform device
in the board-*.c along with the list of BT/FM/GPS chip enable
gpio configuration
