MIPS: bcm3384: Initial commit of bcm3384 platform support

This supports SMP Linux running on the BCM3384 Zephyr (BMIPS5000)
application processor, with fully functional UART and USB 1.1/2.0.
Device Tree is used to configure the following items:

 - All peripherals
 - Early console base address
 - SMP or UP mode
 - MIPS counter frequency
 - Memory size / regions
 - DMA offset
 - Kernel command line

The DT-enabled bootloader and build instructions are posted at
