msm: ipa: removing apps IPv4 & IPv6 filtering partitions from SRAM 



For IPA2.5 and on, the apps IPv4 & IPv6 filetring tables are moved
to DDR, so the corresponding partitions are removed from SRAM.
The space released from these partitions is added to modem memory
partition, since Q6 requires more memory in SRAM for filtering rules.
