Disable CORTEX_ENABLE_WFI_IDLE for kinesis/kint41.

[JiddoDev]

Fix for #24865.
CORTEX_ENABLE_WFI_IDLE was globally enabled for all keyboards in 416af01. This breaks the Teensy 4.0. This change explicitly disables WFI idle for kinesis/kint41.

This breaks the Teensy 4.0

Probably because, like the rest of the Teensy 4.x implementation in ChibiOS, it's very unfinished. Please fix it there.

I have no idea how to get WFI idle to work in ChibiOS. Does it not make sense to selectively disable it for this particular keyboard until that feature works properly?

Only if we can guarantee someone is going to get it to work properly, then come back and revert this. As it stands this is an issue in ChibiOS, not the board.
