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.
