* cleanup keyboards/helix/{rev2|rev3_5rows}/keymaps/five_rows
* Made the layout data easier to read.
* helix/rev2/keymaps/five_rows/keymap.c
* helix/rev3_5rows/keymaps/five_rows/keymap.c
* The following two were made the same.
* keymaps/five_rows/config.h
* keymaps/five_rows/oled_display.c
The binary of the compilation result has not changed.
* update keyboards/helix/rev2/keymaps/five_rows/rules.mk
KEYBOARD_LOCAL_FEATURES_MK was moved to the end.
* add '#define DISABLE_SYNC_TIMER' into helix/rev3_5rows/keymaps/five_rows/config.h
The sync timer features worsen the matrix scan rate of the Helix keyboard. I'm not sure if it makes sense to have sync timer features enabled on the Helix keyboard. So in my keymap I disable this.
* Makes the OLED driver used by the helix:five_rows keymap switchable.
* use TOP/drivers/oled/oled_driver.c
`make HELIX=stdole helix:five_rows`
* use helix/local_drivers/ssd1306.c
`make HELIX=oled helix:five_rows`
* Separated the OLED related code from keymap.c and moved it to oled_display.c.
* scan rate without OLED

* clean up helix/rev2/keymaps/five_rows/keymap.c
* update five_rows/oled_display.c
* update helix/rev2/keymaps/five_rows/keymap.c: remove LAYOUT_kc()
* Ported the keymap from helix/rev2:five_rows to helix/rev3_5rows:five_rows.
* update five_rows/oled_display.c
* add License comment
