Subject: [PATCH v8 04/14] arm64: dts: qcom: sc7180: Fix the base addresses of LLCC banks

The LLCC block has several banks each with a different base address
and holes in between. So it is not a correct approach to cover these
banks with a single offset/size. Instead, the individual bank's base
address needs to be specified in devicetree with the exact size.

On SC7180, there is only one LLCC bank available. So let's just pass that
as "llcc0_base".
