linux-postmarketos-qcom-sdm845: Improve work-around for call audio regressions (MR 6032)

Browse source 
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 until the issue is resolved upstream.

Previously, the module's was modified to disable the in-kernel PD
mapper. This modification was a hack. Instead, modify the config so that
the in-kernel PD mapper is not built in the first place, which achieves
the same result.

Subject: [PATCH] HACK: remoteproc: qcom: disable in-kernel PD mapper
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.
