net: Fix Hisilicon Network Subsystem Support Compilation

This patch fixes the compilation error with arm allmodconfig, this error
generated due to unavailability of readq() on 32-bit platform which was
found during net-next daily compilation. In the same time, fix all the
hns drivers compilation warnings.
