boards/intel_adsp_cavs15: Add alternative integration tool for twister
The twister integration on this board is problematic:
+ It assumes that it will be building on the device's linux
installation, which is often a somewhat slow Apollo Lake board (Up
Squared) with extremely limited storage space (mine has only 5G left
on the internal eMMC after Zephyr installation and can't fit a full
twister build tree).
+ Reading the trace output before the firmware load will emit output
from a previous test run. Twister isn't consistent about the order
in which the --west-flash and --device-serial-pty scripts are
started, which means that tests show spurious failures when the
order changes or if the device started with a test in its trace
buffer.
This is an elaboration on the scripting I've been using. It's a
single script that works as both the west-flash and device-serial-pty
handlers (or as an all-in-one standalone if you pass it the path to
the zephyr.elf file instead of running it under twister). It reaches
the device host over ssh and runs the tools with sudo, minimizing
administration overhead (the device does need a checked-out Zephyr
tree and a built diag_driver kernel module though).
