ANDROID: input: Add vendor hook for __pass_event in evdev.c

Add vendor hook for passing events to client drivers.

We have some limitation to achieve the goal of input performance
without modification of kernel. So I would like you to add vendor
hook and please review the reason why I want to add it.

As the users trigger input actions, we need to support the input
operation and the what the users want to do so that there's no delay.
So we've developed and used "input booster" controling some resources
properly during input operations according to input type.

Android already has the booster in framework to support input actions
however this way has a long latency to control resources.

To reduce latency, we've placed the booster in kernel side for high
responsiveness and it guarantees faster than framework booster.
In addtion, I applied Samsung's own concept to the booster.
And it has been operated stably on all Galaxy models for about 10 years.

So we need
  - add function to notify input events delivered to client in evdev.
