This adds support for the Microchip PIC32 MIPS microcontroller with the specific variant PIC32MZDA. PIC32MZDA is based on the MIPS m14KEc core and boots using device tree. This includes an early pin setup and early clock setup needed prior to device tree being initialized. In additon, an interface is provided to synchronize access to registers shared across several peripherals.
