Add support for the MIPS firmware processor, used in the Series AXE GPU.
The MIPS firmware processor uses a separate MMU to the rest of the GPU, so
this patch adds support for that as well.

Changes since v8:
- Corrected license identifiers

Changes since v6:
- Fix integer overflow in VM map error path

Changes since v5:
- Use alloc_page() when allocating MIPS pagetable

Changes since v3:
- Get regs resource (removed from GPU resources commit)
