* Ensure that n-key rollover is used

* Port changes to other launch boards

* Configuration values for starting HSV and speed (#7740)

* Define default HSV and speed for RGB matrix.

* Documentation for configuration values RGB_MATRIX_STARTUP_HUE, RGB_MATRIX_STARTUP_SAT and RGB_MATRIX_STARTUP_VAL.

* Document RGB_MATRIX_STARTUP_SPD.

* Preserve the ordering.

* Set default RGB mode, hue, and saturation

* Reduce AVR clock to 8MHz

* Update launch_beta_1 with new USB ID

* Update default LED mode

* Add reset to bootloader command for Launch keyboard

* Rename launch_beta_1 to launch_1

* Enable LTO when compiling for launch_1

* Allow setting individual LED's

* Convert tabs to spaces

* Unlock on RESET keypress:
- Display unlock pattern
- Disable LED get/set functions
- Enable reset to bootloader function

* Reduce brightness of rainbow backdrop in unlock pattern

* Add hid commands for setting led matrix mode

This changes the color setting to not change the mode, and set the hue
and saturation for QMK effects.

* Fix `CMD_LED_GET_MODE`

* Add Levi's Launch layout

* Fix layer mistake in Levi's Launch layout

* Add matrix command

* Define default RGB matrix speed

* Add active_keys effect

* Move definition of RGB modes inside ifdef testing for custom RGB modes

* RGB parameters per layer

* fix: Call `system76_ec_rgb_layer` after setting mode

* Include layer 3 and 4 in default layout for launch_1

I added support for layer 3 and 4 to the Configurator, but it seems to
load bogus values.

`dynamic_keymap_reset()` has a comment saying:
```
// Reset the keymaps in EEPROM to what is in flash.
// All keyboards using dynamic keymaps should define a layout
// for the same number of layers as DYNAMIC_KEYMAP_LAYER_COUNT
```

Other keyboards seem to have default layouts that only list the first
two layers while setting `DYNAMIC_KEYMAP_LAYER_COUNT` to 4, but
whatever. This appears to make the Configurator behave as expected with
layer 3 and 4.

* Use EEPROM to store RGB parameters

* Add layer 2 and 3 to other keymaps

* Add LED_SAVE command

* Use eeprom_update_block to improve performance

* Revert "Configuration values for starting HSV and speed (#7740)"

This reverts commit de1f60fd370b4769336b8a707ee12657aee46412.

* Update launch_1 rules.mk for changes in Qmk

* WIP keycodes matching EC behavior

* Modify default layout to match design

* Apply updates to jeremy layout

* launch_1: Use `KC_NO` instead of `KC_TRNS` for default layout

* Revert "launch_1: Use `KC_NO` instead of `KC_TRNS` for default layout"

This reverts commit f71c5e7ac3cecbbb1a1f8934db1f329407fef041.
