firehose: Increase timeout for read of program-ack

Commit 'a10cf7f5da7a ("firehose: Increase image write timeout to 60
seconds")' bumped the timeout for writes in the program operation, per
observed behavior. This was confirmed to solve the problems seen when
programming SPINOR in Nord devices

New reports (and measurements) shows the write taking a negligible
amount of time and the read of the following "program ack" taking the
whole reported ~35 second, resulting in a timeout.

The proprietary tools has a write timeout of 60 seconds in some
operating systems and no timeout for others, and a read timeout of 120
seconds.

Update this timeout for the "program ack" to 120 seconds, to match the
proprietary tools.
