bus: bt1-apb: 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.
