Ok, got it working now (at least it seems to be working, checking
remotely on my panda).

Besides enabling uim, had also to fix the firmware path, otherwise the load would fail, like:
[   23.130584] (stc): st_tty_open 
[   23.133758] (stk) : line discipline installed 
[   23.139068] (stk) :TIInit_7.2.31.bts
[   23.151763] (stk) : request_firmware failed(errno -2) for TIInit_7.2.31.bts
[   23.160278] (stk) :download firmware failed
[   23.164855] (stk) :ldisc_install = 0
[   23.168975] (stc): st_tty_close 

At least at the linux-firmware (1.60) package, this firmware is located at /lib/firmware/ti-connectivity/TIInit_7.2.31.bts, but the drivers requires it to be located at /lib/firmware instead:
drivers/misc/ti-st/st_kim.c:	sprintf(bts_scr_name, "TIInit_%d.%d.%d.bts", chip, maj_ver, min_ver);

Checking wl12xx, it points the correct firmware directory for the module
(ti-connectivity/wl1271-nvs.bin), so one fix is to change the default
path to match the one provided by linux-firmware. I believe there could
be a workaround at udev, but need further investigation.
