Subject: [PATCH 03/16] x86: Make default_send_IPI_mask_sequence/allbutself_logical() 32bit only

Both functions are used only in 32bit.  Put them inside CONFIG_X86_32.
This is to prepare for logical apicid handling update.

- Cyrill Gorcunov spotted that I forgot to move declarations in ipi.h
  under CONFIG_X86_32.  Fixed.
