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.
