Subject: [PATCH 4/5] arm64: dts: amazon: alpine-v3: drop cache nodes unit addresses

Cache device nodes within cpus do not have "reg" property, so should not
have unit address, as reported by dtc W=1 warnings:

  alpine-v3.dtsi:247.24-254.5: Warning (unit_address_vs_reg): /cpus/cache@0: node has a unit name, but no reg or ranges property
  alpine-v3.dtsi:256.26-263.5: Warning (unit_address_vs_reg): /cpus/cache@100: node has a unit name, but no reg or ranges property
  alpine-v3.dtsi:265.26-272.5: Warning (unit_address_vs_reg): /cpus/cache@200: node has a unit name, but no reg or ranges property
  alpine-v3.dtsi:274.26-281.5: Warning (unit_address_vs_reg): /cpus/cache@300: node has a unit name, but no reg or ranges property
