linux-postmarketos-qcom-sdm845: Work-around call audio regressions (MR 5966)

Somehow enabling in-kernel PD mapper (introduced in 5b9f51b200dcb
"remoteproc: qcom: enable in-kernel PD mapper"), breaks the bottom mic
on xiaomi-beryllium (Poco F1) and distorts audio on OP6 (and possibly
OP6T). Temporarily disable it and log the rprocs in use until we better
understand what causes the issue.
