irqchips/bmips: Add bcm6345-l1 interrupt controller

Browse Source 
Add the BCM6345 interrupt controller based on the SMP-capable BCM7038
and the BCM3380 but with packed interrupt registers.

Add the BCM6345 interrupt controller to a list with the existing BCM7038
so that interrupts on CPU1 are not ignored.

Update the maintainers file list for BMIPS to include this driver.
