Log Message:
bcm2711: patch cpus "enable-method" in dts and use it on initialization

The upstream bcm2711.dtsi returns "brcm,bcm2836-smp" as "enable-method" on
/cpus node but bcm2711 requires different addresses from bcm2836.

Fixes early panic on Raspberry Pi 4B with earmv7hf MULITIPROCESSOR kernel:
