cris: Remove ELF_MACHINE from cpu.h

The only generic code relying on this is linux-user, but linux users'
default behaviour of defaulting ELF_MACHINE to ELF_ARCH will handle
this.

The bootloader can just pass EM_CRIS directly, as that is architecture
specific code.

This removes another architecture specific definition from the global
namespace.
