Just to clarify, the main part there is a bugfix ;) Only the first
IRQ from the SYS_timer was delivered to the ARM core. It passed my
smoke test because when I wrote the model only u-boot was using this
peripheral, then Linux started to use it.

Fixes: 0e5bbd74064 ("hw/arm/bcm2835_peripherals: Use the SYS_timer")
