Currently the lowest "real" irq number for the XICS irq controller (as
opposed to numbers reserved for IPIs and other special purposes) is
hard coded as 16 in two places - in xics_system_init() and in spapr.c.
As well as being generally bad practice, we're going to need to change this
number soon to fit in with the in-kernel XICS implementation. This patch
adds a #define for this number to avoid future breakage.
