19824: boards/sipeed_longan_nano: separate board definition for Sipeed Longan Nano TFT r=benpicco a=gschorcht ### Contribution description This PR provides a minimal separate board definition for the Sipeed Longan Nano version with TFT display which is just an extension of `boards/sipeed-longan-nano` with enabled TFT display module. From the lessons we had to learn with the Kconfig modelling of optional hardware, the TFT version of the Sipeed Longan Nano board has been split off into its own board definition based on the existing Siepeed Longan Nano board. Commits ba29a5e, 237819e, 6d8b56d and c5faf34 are small cleanups of peripheral configurations and could be split from this PR as follow-up PR (changes +70 -36). ### Testing procedure Green CI ``` BOARD=sipeed-longan-nano-tft make -j8 -C tests/drivers/st77xx flash ``` should work ### Issues/PRs references Follow up to PR #19813 and PR #19814 Prerequisite for PR #19825 and PR #19827 19855: gnrc_static: fix static PID assignment r=benpicco a=benpicco Co-authored-by: Gunar Schorcht <gunar@schorcht.net> Co-authored-by: Benjamin Valentin <benjamin.valentin@bht-berlin.de>
