percpu: remove PER_CPU_DEF_ATTRIBUTES macro

The macro is not used:

  $ grep -r PER_CPU_DEF_ATTRIBUTES
  include/linux/percpu-defs.h:	__PCPU_ATTRS(sec) PER_CPU_DEF_ATTRIBUTES __weak		\
  include/linux/percpu-defs.h:	__PCPU_ATTRS(sec) PER_CPU_DEF_ATTRIBUTES		\
  include/asm-generic/percpu.h:#ifndef PER_CPU_DEF_ATTRIBUTES
  include/asm-generic/percpu.h:#define PER_CPU_DEF_ATTRIBUTES

It was added with b01e8dc34379 ("alpha: fix percpu build breakage") and
removed in 2009 with b01e8dc34379..6088464cf1ae.
