From: Yan-Hsuan Chuang <yhchuang@xxxxxxxxxxx>
The inlined rtw_write32s_mask has to check range of addr with
BUILD_BUG_ON. But with some variants of gcc version the function might
not get inlined, and it will have no idea to know how to do, then
results in a compile error. Turn it into a macro to make sure the values
are known when compile time.
