ports/teensy: Remove teensy port.

ports

This port is largely unmaintained, has limited features, and only supports a small number of teensy boards, and can be confused with the mimxrt support for Teensy 4.x.

Assessment

Q Qwen · high

The query asks about SDIO support for Teensy 4.1 (which uses the i.MXRT chip, handled by the mimxrt port). The candidate PR removes the old 'teensy' port (which supported Teensy 3.x with MK20DX chips) and explicitly mentions that it can be confused with the mimxrt support for Teensy 4.x. While the PR addresses the confusion between the two ports and removes the unmaintained one, it does not answer the specific question about SDIO support in the mimxrt port. The PR is related because it clarifies the port architecture, but it doesn't resolve the query about SDIO capabilities.

Suggested action

Keep the issue open. The PR removes the old teensy port but does not provide information about SDIO support in the mimxrt port. The issue should be answered by checking the mimxrt port's sdcard.c implementation or creating a new issue/PR to add SDIO support if it's missing.
