There are some customer specific boards with 4 timers but they use out of tree drivers. Now that the timer 'channels' are handled correctly in the subdevice functions, fix the number of timer channels for the subdevice and remove the code that would access a 4th timer. Also, remove the unnecessary initialzation of the subdevice 'len_chanlist'. That member is only used by subdevices that support async commands.
