Sebastian Reichel 87d99063be HSI: ssi-protocol: Use handshake logic from n950
When using the ssi-protocol driver with the Nokia N950, the
following error is thrown during modem powered up sequence.

This patch fixes the issue by using the handshake setup from
the Nokia N950 kernel. The new handshake sequence also works
with the N900, so there is no need to differentiate between
both modems.
