drivers:misc: ti-st: move from rfkill to sysfs
The communication between ST KIM and UIM was interfaced over the /dev/rfkill device node. Move the interface to a simpler less abusive sysfs entry mechanism and document it in Documentation/ABI/testing/ under sysfs-platform-kim. Shared transport driver would now read the UART details originally received by bootloader or firmware as platform data. The data read will be shared over sysfs entries for the user-space UIM or other n/w manager/plugins to be read, and assist the driver by opening up the UART, setting the baud-rate and installing the line discipline.
