ARM: dts: qcom: use property “iommu-addresses” for UFSHC

Browse Source 
The upstream commit <a5bf3cfce8cb7>
("iommu: Implement of_iommu_get_resv_regions()")
has added a devicetree property "iommu-addresses", which
describes to the DMA api what IOVA addresses a device
can/cannot use. So we replace “qcom,iommu-dma-addr-pool”
by “iommu-addresses” since kernel 6.5 to follow upstream.
