cherry: code cleanupstabilize-rust-14220.B-main

1) remove board_overcurrent_event since CL:2532676 added a default empty
   implementation
2) remove GPIO_EN_KB_BL control since it's already handled in
   keyboard_backlight.c
3) remove unused header includes
4) remove unused it5205 sbu handler

BUG=none
TEST=make
BRANCH=main
