mptable: Refactor lintsrc generation
We copied pretty much the same code for generating mptable entries for
local interrupts (with some notable exceptions).
This change moves these lines into a generic function "mptable_lintsrc"
and makes use of it in many places.
The remaining uses of smp_write_lintsrc should be reviewed and replaced
by mptable_lintsrc calls where possible, and smp_write_lintsrc made static.
This patch was generated using Coccinelle:
