i2c: mux: pca9541: Use I2C adapter timeout value for arbitration timeout

Remove existing arbitration timeout macros and use I2C adapter timeout
value for arbitration timeout and forceful bus ownership.

I2C adapter timeout can be configurable from user space, so using it
for arbitration timeout helps in configuring the arbitration timeout
from user space depending on the use case.
