As Mark suggests, the driver should handle this register as a special case.

One way the solve the problem is via the st.cmd configuration command 
for the driver.
Add an extra argument, which is the initialization value for the 
configuration register.
Do the initialization either when the configuration command is executed 
or during the first port connect.
