bus: bt1-axi: Use sysfs_streq instead of strncmp 

There is a ready-to-use method to compare a retrieved from a sysfs node
string with another string. It treats both NUL and newline-then-NUL as
equivalent string terminations. So use it instead of manually truncating
the line length in the strncmp() method.
