adi_ip.tcl: adi_add_bus_clock: Set polarity depending on the reset name suffix 

Currently the polarity of the reset signal is always set to negative.
Change this so that the polarity is selected on the suffix of the name. If
it ends with a 'n' or 'N' the polarity will be negative, otherwise it will
be positive.

This allows this function to be used with reset signals that have positive
polarity.
