alpha: unbreak percpu again
Commit 9b8de7479d0dbab1ed98b5b015d44232c9d3d08e ("FRV: Fix the section attribute on UP DECLARE_PER_CPU()") cleaned up DECLARE/DEFINE_PER_CPU() macros and in the process made alpha percpu.h include include/asm-generic/percpu.h which breaks compilation due to duplicate definitions. Remove inclusion of generic asm helper file and define whatever necessary in alpha header proper. In the longer term, percpu definitions will be unified and all these little subtlties will be removed.
