internal/cpu: make architectures without initialization work explicit

When cpu_no_init.go was created most architectures did not have
code in the doinit function. Currently only mips(le), riscv64 and
wasm do not have empty doinit functions.

Keeping cpu_no_init.go around does not reduce the work to satisfy
the build process when adding support for new architectures.

To support a new architecture a new file or build directive has to
be added to an existing file at any rate to define the constant
CacheLinePadSize. A new empty doinit can then be created in the
new file or the existing doinit can be reused when adding the
additional build directive.
