RDMA/hns: Fix GID capacity loss in 64K system
Our HW always handles GMV BT pages with a fixed 4K size, but the driver
calculates the needed GMV BT pages number with PAGE_SIZE, which is 64K
in 64K system. Only the first 4K (GMV index 0-127) can be reached by HW,
causing GID capacity loss and memory waste.
Split a single 64K BT page into multiple 4K pages and register them to
HW per 4K block so that HW can correctly reach all GMV entries.
