Set SN74HC165's clock_inhibit_pin as optional 

The use of only 3 pins is mentioned, but the configuration values don't reflect that.
Datasheet specifies the pin can be directly connected to ground. The code already expects the pin to not be used: ec3162282c/esphome/components/sn74hc165/__init__.py (L35)

@ -11,6 +11,8 @@ Once configured, you can use any of the 8 pins for your projects. Up-to 256 shif
to provide more pins, without using more GPIO pins on the controller. They are linked by connecting pin Q of the closer
shift register to the pin QH of the next shift register.
The use of CLK INH pin is optional, as it can be directly connected to ground.
