[PATCH 13/35] arm64: dts: qcom: sc8280xp: Fix PDC reg size to single APSS DRV region

From: Mukesh Ojha

Date: Fri Apr 10 2026 - 14:49:05 EST


The PDC reg size was 0x30000, covering three DRV regions. Linux only
needs the APSS DRV region which is a single 0x10000 window. Reduce
the size to 0x10000 to describe only the region actually used.
