Enables SMP IRQ affinity API (/proc/irq/*/smp_affinity, etc.)
for SMTC Linux kernel. Requires platform support, of which
an example can be found in the MIPS kernel i8259 and Malta
platform code. It is recommended that MIPS_MT_SMTC_INSTANT_REPLAY
be enabled if MIPS_MT_SMTC_IRQAFF is used. Adds overhead to
interrupt dispatch, and should be used only if you know what
you are doing.
