milkymist-minimac2: Flush queued packets when link comes up

Drop .can_receive and move the semantics into minimac2_rx, by returning
0.

That is once minimac2_rx returns 0, incoming packets will be queued
until the queue is explicitly flushed. We do this when s->regs[R_STATE0]
or s->regs[R_STATE1] is changed in minimac2_write.

Also drop the unused trace point.
