check-sof-logger: fix the DSP boot check

The DSP boot check reload_drivers() must wait longer than 5 seconds as
we have many configurations where DSP boot will take more than 60sec
(due to e.g. Intel platforms with i915 hardware present but driver not
present in the kernel version under test).

Additionally the test case must check whether DSP did boot
up after the timeout expires, and fail the test case if it
didn't.
