but the __init marker is missing, so add it to these three platforms.

Since v1:
- add __init marker to trap_init() for alpha, microblaze and sparc32
- adjust the generic weak NOP trap_init() location to make it sits with

Many architectures implement the trap_init() as NOP, since there is
no such default for trap_init(), this empty stub is duplicated among
these architectures. Provide a generic but weak NOP implementation
to drop the empty stubs of trap_init() in these architectures.
