pwm: tachometer: Remove unused APIs

Browse Source 
From Linux kernel version 6.0, some of the callback ops are
removed from pwm like config, enable, disable.

Remove the implementation of these callbacks for Linux kernel
version 6.0 and above. Add the required callback for version 6.0

Note: This change is not tested on V6.0. This is the compilation fix.
