The irq to block mapping is fixed, and interrupts from the first block

themselves can be routed to any available CPU.
This is used by the bootloader to map the first parent interrupt to the
boot CPU, regardless wether the boot CPU is the first one or the second
one.
When booting from the second CPU, the assumption that the first block's
IRQ is mapped to the first CPU breaks, and the system hangs because
interrupts do not get routed correctly.
Fix this by passing the appropriate bcm6434_l1_cpu to the interrupt
handler instead of the chip itself, so the handler always has the right
block.
