455a4c46e023ab84263eae0fc7acca9a5ee8b7ac | Analyze and fix the following issue in the Linux kernel code: ARM: dts: qcom: strip prefix from PMIC files | Problem Details:
As the vendor DTS files were moved to per-vendor subdirs, there no need
to use common prefixes. Drop the `qcom-' prefix from PMIC dtsi file.
This makes 32-bit qcom/ dts files closer to arm64 ones.
