feat(board): add puchi_ble_v1 to boards

[BenRoe]

Board/Shield Check-list

• This board/shield is tested working on real hardware
• Definitions follow the general style of other shields/boards upstream (Reference)
• .zmk.yml metadata file added
• Proper Copyright + License headers added to applicable files (Generally, we stick to "The ZMK Contributors" for copyrights to help avoid churn when files get edited)
• General consistent formatting of DeviceTree files
• Keymaps do not use deprecated key defines (Check using the upgrader tool)
• &pro_micro used in favor of &pro_micro_d/a if applicable
• If split, no name added for the right/peripheral half
• Kconfig.defconfig file correctly wraps all configuration in conditional on the shield symbol
• .conf file has optional extra features commented out
• Keyboard/PCB is part of a shipped group buy or is generally available in stock to purchase (OSH/personal projects without general availability should create a zmk-config repo instead)

Hi,
my name is Ben from Keycapsss.com. The Puchi-BLE is a nrfMicro 1.3 fork.
I am in contact with @joric (creator of the nrfMicro). He is fine with the fork.
The board is tested and works.

I have encapsulate board (nrfmicro_13 -> puchi_ble_v1) for future changes.
I am not sure if all files have proper Copyright + License headers. If something is missing, let me know and i will change it.

Please be sure to check all the copyright and license headers on every file.

Thanks!

@petejohanson all requested code changes should be fixed now.

Just one outstanding question.
