sync the left and right backlight led control on ErgoDash (#3298)

* Hardware update

Backlight enable
Change pin
Add 2keys (68→70)

* change readme

* support rev1

change keymap path

* move ergodash.h

* sync the left and right backlight led

matrix.c is same as iris keyboad
backlight breathing is unstable,  so it comment out
