irqchip: bcm7120-l2: Decouple driver from brcmstb-l2

Some chips, such as BCM6328, only require bcm7120-l2.  Some BCM7xxx STB
configurations only require brcmstb-l2.  Treat them as two separate
entities, and update the mach-bcm dependencies to reflect the change.

          Say Y if you intend to run the kernel on a Broadcom ARM-based STB
          chipset.
