arm64: dts: qcom: sm8650: Fix CDSP context banks unit addresses
[ Upstream commit ff2b76ae689b71e2d7a2e70bfd8d71537c39164d ]
There is a mismatch between 'reg' property and unit address for last
there CDSP compute context banks. Current values were taken as-is from
downstream source. Considering that 'reg' is used by Linux driver as
SID of context bank and that least significant bytes of IOMMU value
match the 'reg', assume the unit-address is wrong and needs fixing.
This also won't have any practical impact, except adhering to Devicetree
spec.
