riscv: smp: Move enum ipi_message_type to asm/smp.h

The IPI message type enumeration (and therefore IPI_MAX) is currently
private to arch/riscv/kernel/smp.c.  Several IPI providers need to know
the exact number of IPIs that the architecture requires, so move the
enum into the public header.

This is a pure code movement with no functional change.
