The variable fin_freq is being initialized with a value that is never
read and it is being updated later with a new value. The initialization
is redundant and can be removed.

This was introduced in 211ed630753d ("pwm: Add support for Meson PWM
Controller"), adding Neil To Cc:.
I don't think this was added to cope for a compiler not being able to
see the variable is used initialized only.
