    IRQCHIP: bcm7120-l2: Split STB-specific logic into its own function · ca40f1b2

    The BCM7xxx instances of this block (listed in the register manual as
    simply "IRQ0") all have the following items in common:
    
     - brcm,int-map-mask: for routing different bits in the L2 to different
       parent IRQs
    
     - brcm,int-fwd-mask: for hardwiring certain IRQs to bypass the L2 and
       use dedicated L1 lines
    
     - one enable/status pair (32 bits only)
    
    Much of the driver code can be shared with BCM3380-style controllers, but
    in order to do this cleanly, let's split out the BCM7xxx-specific logic
    first.
