[Keybooard] Update of Ergodash Keyboard (#5772)

* Simpler coding

use SPLIT_KEYBOARD
delete rev1 (rev2→rev1)  because rev1is not sold

* delete USE_I2C = no

* Update readme.md

See [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) then the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information.

Install Example: (for pro micro)
    `make ergodash/rev2:default:avrdude`
  
    `make ergodash/rev1:default:avrdude`

Note:  
  "rev2" is for PCB ver 1.1,1.2  
  "rev1" is from earlier pcb
  "rev1" is for PCB ver 1.0,1.1,1.2  
  **The original Rev 1 was owned only by the designer. Therefore, Rev1 has been removed. Since the current PCB is Rev1, we changed Rev2 to Rev1 to match the firmware version.**
