Subject: [PATCH v2 2/2] tyr: remove impl Send/Sync for TyrData

Now that clk implements Send and Sync, we no longer need to manually
implement these traits for TyrData. Thus remove the implementations.

The comment also mentions the regulator. However, the regulator had the
traits added in commit 9a200cbdb543 ("rust: regulator: implement Send
and Sync for Regulator<T>"), which is already in mainline.
