[mips/broadcom] Add initial support for Broadcom MIPS processor
Relies on BHND(4) driver. There files contains machine-dependent code for Broadcom MIPS processor and provide UART driver. This is a work in progress; it and the current bhnd code is enough to boot on the ASUS RT-N16 and RT-N53 platforms.
