bcm63xx: periph_intc: report effective affinity
The bcm6345-periph-intc driver only targets a single CPU at a time, even if the notional affinity is wider. Let's inform the core code about this. This patch gets rid of the kernel message: "genirq: irq_chip bcm6345-periph-intc did not update eff. affinity mask of irq 52" Signed-off-by: Daniel Gonzalez Cabanelas <dgcbueu@gmail.com> Signed-off-by: Álvaro Fernández Rojas <noltari@gmail.com> (cherry picked from commit e04ff3c7cc52c23f5b40730ee426710e22940d68)
