qcacld-3.0: Change dma address size to 8 bytes for Genoa IPA

Browse source 
Currently, sizeof(qdf_dma_addr_t) is 4 bytes, but IPA driver
and WLAN FW always use 8 bytes, we should follow up with them,
otherwise, the numbers of rx complete ring entries will not be
same in both sides. Meanwhile, for tx complete ring, during the
first time initialization, we fill the buffer address with 4
bytes, while GSI FW read 8 bytes address content from tx complete
ring, which should cause the GSI FW get invalid address on the half
way and cause the smmu fault issue. So fill 8 bytes length buffer
address to the tx complete ring can avoid such issue.
