Kenneth Aloysius f2bc70a264 ps2avrgb: fix incorrect avr ports specified (for numlock and capslock LEDs) (#3453)
* Add M6-A keymap

* Update XD60 keymap

* Update XD60 keymap readme

* Update JJ40 and Let's Split keymaps

* Add readme for M6-A

* Fix typo, update JJ40 README

* Update jj40 readme

* Cleanup jj40 keymap

* Revert Let's Split QWERTY layer to default before #2010

* Update numpad layers

* Fix: Let's Split keymap getting stuck mods due to having keycodes assigned on the Raise layer

* Keep ASCII art consistent with keymap

* Staryu: initial port

* Add personal keymap

* Added and updated READMEs

* Fix: default keymap for staryu

* Rudimentary backlight support.

* Enabled mousekeys for default keymap

* use QMK_KEYBOARD_H and LAYOUT

* Update readme.md for NIU mini: flash using avrdude

* Fix missing linebreaks for Staryu README

* Update readme.md

* Update PS2AVRGB boards with new matrix.c

* Update canoe matrix.c; untested

* Fix canoe.c for building (needs matrix_scan_user and matrix_init_user)

* Add personal Iris keymap

* Update keymap

* Update keymap

* Update keymap, disable backlighting and underglow

* Move PrintScreen button

* Add README

* Update personal keymaps

* Add INS key

* Limit USB max power consumption, change Fn to MENU

* Remove Numpad layer (easy to accidentally toggle)

* Fix backlighting for ps2avrgb

* Update comments to refer to actual pin naming

* Possible fix for xyverz ortho keymap: define RGBLED_NUM

* Make led_set_user in backlight.c overridable

* Add changes to address points raised in code review, untested (don't have build env right now)
