David Wei 39f8fcda20 bnxt: fill data page pool with frags if PAGE_SIZE > BNXT_RX_PAGE_SIZE 
The data page pool always fills the HW rx ring with pages. On arm64 with
64K pages, this will waste _at least_ 32K of memory per entry in the rx
ring.

Fix by fragmenting the pages if PAGE_SIZE > BNXT_RX_PAGE_SIZE. This
makes the data page pool the same as the header pool.

Tested with iperf3 with a small (64 entries) rx ring to encourage buffer
circulation.

Fixes: cd1fafe7da ("eth: bnxt: add support rx side device memory TCP")
