Subject: [PATCH 1/2] arm64: dts: qcom: qdu1000: correct LLCC reg entries

According to bindings and Linux driver there is no
"multi_channel_register" address space for LLCC.  The first "reg" entry
is supposed to be llcc0_base since commit 43aa006e074c ("dt-bindings:
arm: msm: Fix register regions used for LLCC banks"):

  qdu1000-idp.dtb: system-cache-controller@...00000: reg: [[0, 421527552, 0, 14155776], [0, 438304768, 0, 524288], [0, 572293416, 0, 4]] is too long
  qdu1000-idp.dtb: system-cache-controller@...00000: reg-names:0: 'llcc0_base' was expected
  qdu1000-idp.dtb: system-cache-controller@...00000: reg-names: ['llcc_base', 'llcc_broadcast_base', 'multi_channel_register'] is too long
