Every architecture supported by the kernel has a functionally identical
copy of <asm/asm-offsets.h> which simply includes
<generated/asm-offsets.h>, even though it is also present in
asm-generic. Eliminate this unnecessary complexity by adding
<asm/asm-offsets.h> to the list of mandatory asm headers, which causes
a copy of it that includes <asm-generic/asm-offsets.h> to be generated
automatically.
