hsi_ffl_tty: increase modem boot timeout to 60 seconds as per IMC request

BZ: 28292

The modem post boot handshake timeout is currently set to 10 seconds, which
seems to be sufficient a time for the modem to setup its HSI IPC. But, this
assertion is not true and the modem can take up to one minute to boot up.

This patch is simply increasing the modem boot timeout to 60 seconds instead
of 10 seconds to allow correct modem reboot handshake in all contexts.

Still, this timeout value shall be fine tuned when the modem firmware will be
allowing shorter boot sequences - one minute seems huge for setting up the IPC.
