tsec: Fix a bug in soft-resetting
SOFT_RESET must be asserted for at least 3 TX clocks. Usually, that's about 30
clock cycles, so it's been mostly working. But we had no guarantee, and at
slower bitrates, it's just over a microsecond (over 1000 clock cycles). This
enforces a 2 microsecond gap between assertion and deassertion.
