Subject: [PATCH v2] arm64: dts: berlin4ct: switch to Cortex-A53 specific pmu nodes

Commit ac82d1277215 ("arm64: perf: add Cortex-A53 support") adds the
cortex A53 PMU support, thus instead of using the generic armv8-pmuv3
compatibility use the more specific Cortex A53 compatibility.

Signed-off-by: Jisheng Zhang <jszhang@...vell.com>

Since v1:
 - keep "arm,armv8-pmuv3" as a fallback in the compatible list. Thank
   Arnd and Mark.
