Subject: [PATCH v2] rch/score/include/uapi/asm/ptrace.h: Add prefix 'SCORE_'
 for related macros

'COUNTER' and other same kind macros are too common to use, and easy to
get conflict with other modules. So add prefix for them.

And it is UAPI, so only change it within linux kernel.

The related warning (allmodconfig with score):

    CC [M]  drivers/md/raid1.o
  In file included from drivers/md/raid1.c:42:0:
  drivers/md/bitmap.h:93:0: warning: "COUNTER" redefined

  ./arch/score/include/uapi/asm/ptrace.h:13:0: note: this is the location of the previous definition
   #define COUNTER  38
