Don't use the static keyword with DPCPU defines in arm64 modules.
On arm64 compiler will create PC-relative loads and stores for static data.
This means it doesn't emit a relocation. Unfortunately the in-kernel linker
expects there to be one for DPCPU defines so it can modify its value so the
code will use the correct DPCPU region.
To workaround the lack of a relocation with static data remove it when
building modules on arm64. The kernel is unaffected as it doesn't rely on
modifying these relocations to find the data.
