RDMA/mana_ib: use the correct page table index based on hardware page size

jira LE-3812
commit-author Long Li <[email protected]>
commit 9e517a8
upstream-diff There were build failures and conflicts due to the
following missing commits :-
e849aad ("RDMA/mana_ib: Fix bug in creation of dma regions")
071bade ("net: mana: Add support for page sizes other than 4KB on ARM64")
5861cd1 ("net: mana: Enable MANA driver on ARM64 with 4K page size")

MANA hardware uses 4k page size. When calculating the page table index,
it should use the hardware page size, not the system page size.
