linux-postmarketos-qcom-sdm845: Improve work-around for call audio regressions

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.
