qcom: rename Lenovo ThinkPad X13s firmware paths

After some discussion with Bjorn, the Qualcomm platform maintainer, it
was agreed to follow the established practice and to inject the SoC name
into the firmware paths.

It is highly unlikely that we are going to run Linux off the existing
ACPI data in these platforms anytime soon. And even if we do so, we'd
have to figure out the file names anyway, as they do not follow the
existing standard names.
