[BUG] enabling telemetry breaks shell and winconsole

[kv2019i]

Describe the bug
It seems following debug features are broken on multiple Intel targets:

• app/shell_overlay.conf (https://thesofproject.github.io/latest/developer_guides/debugability/shell/index.html)
• app/winconsole_overlay.conf

... it turns out this is related to enabling SOF telemetry with debug window backend in #9186 .

In theory these shouldn't conflict, shell backend is using debug window slot 0 (2.0), while winconsole is using window 3 (3.0), while telemetry is hardcoded to use 2.1.

To Reproduce
Build with above overlays.

Reproduction Rate
100% on Intel LNL.

Expected behavior
telemetry should not affect uses of other memory window users.

Impact
debug feature unavailable

Environment

1. Branch name and commit hash of the 2 repositories: sof (firmware/topology) and linux (kernel driver).
   • Kernel: n/a
   • SOF: f2efd4a
2. Name of the topology file
   • Topology: n/a
3. Name of the platform(s) on which the bug is observed.
   • Platform: Intel lnl

@tobonex @jsarha any ideas? We hit this with @ujfalusi

@kv2019i Window 3 is used by performance measurements. Try disabling CONFIG_SOF_TELEMETRY_PERFORMANCE_MEASUREMENTS to check.

@tobonex thanks, aa, I missed this:

#define ADSP_PMW ((volatile uint32_t *) \
»       »        (sys_cache_uncached_ptr_get((__sparse_force void __sparse_cache *) \
»       »       »       »            (WIN3_MBASE + WIN3_OFFSET))))

So winconsole is clearly conflicting and you can use either/or.

This doesn't explain the conflict with shell, but the shell overlay also enables the winconsole, so maybe that causes the problem.
