Subject: Move disable JTAG code from `keyboard_init` to `keyboard_setup`
X-Git-Url: https://git.donarmstrong.com/?p=qmk_firmware.git;a=commitdiff_plain;h=a5fa75fcb3de822f4e43dcf29cee6eb9f945a992

Move disable JTAG code from `keyboard_init` to `keyboard_setup`

This way all split keyboards are using that code instead of just those using split_common with the fix
