soc/amd/common/include: introduce and use FCH_IRQ_ROUTING_ENTRIES

Instead of using magic constants for the fch_pic_routing and
fch_apic_routing array sizes, define FCH_IRQ_ROUTING_ENTRIES in the
common code headers and use this definition. This also allows to drop
the static assert for the array sizes. In the Stoneyridge mainboard code
the equivalent arrays are named mainboard_picr_data and
mainboard_intr_data; also use FCH_IRQ_ROUTING_ENTRIES as fixed array
size there.
