arm64: dts: qcom: sdm845: Limit ipa iommu streams

Browse Source 
[ Upstream commit 95e6f8467c ]

The Android and Windows firmware does not accept the use of 3 as a mask
to cover the IPA streams. But with 0x721 being related to WiFi and 0x723
being unsed the mapping can be reduced to just cover 0x720 and 0x722,
which is accepted.
