[PATCH v2] net: Fix Hisilicon Network Subsystem Support Compilation

[PATCH v2] net: Fix Hisilicon Network Subsystem Support Compilation

[huangdaode]

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.

Nope, try instead "#include <asm/io-64-nonatomic-lo-hi.h" or
"#include <asm/io-64-nonatomic-hi-lo.h".

yes, it's defined in #include <asm-generic/io-64-nonatomic-hi-lo.h>.
will fix in v3,
