Increase startup reset wait to 2 seconds (#714)

When connecting over a TCP serial socket (e.g. the silabs-multiprotocol
add-on), the NCP reset frame can take ~1.5s to arrive after the remote
reuses the socket from a previous instance. The 1s wait causes a
spurious retry on every startup; bumping to 2s lets the reset land
within the first attempt.
