Subject: [PATCH 5/8] openrisc: Include cpu.h and switch_to.h for prototypes

When compiling with W=1 enabling -Wmissing-prototypes the compiler
warns:

  arch/openrisc/kernel/process.c:100:6: error: no previous prototype for 'arch_cpu_idle' [-Werror=missing-prototypes]
  arch/openrisc/kernel/process.c:240:21: error: no previous prototype for '__switch_to' [-Werror=missing-prototypes]

Fix these by adding the approrpiate header files to process.c which
brings in the prototype definitions.
