Subject: [PATCH v5 06/17] arm64: dts: qcom: sdm845: 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 SDM845, the size of the LLCC bank 0 needs to be reduced to 0x4500 as
there are LLCC BWMON registers located after this range.
