WIP: introduce support for new ngff_cardem board

This adds support for the new ngff_cardem board, a board that basically combines a ngff breakout board with a built-in SIMtrace2. The firmware support added by this ptach is currently untested, and serves as a basis for testing the ngff_cardem prototypes. Change-Id: I9649c853271c22d5403cdf3a7ec9029c9cecfa32

Harald Welte	774330d413	WIP: introduce support for new ngff_cardem board This adds support for the new ngff_cardem board, a board that basically combines a ngff breakout board with a built-in SIMtrace2. The firmware support added by this ptach is currently untested, and serves as a basis for testing the ngff_cardem prototypes.
