ARM: imx: Add AXI address filter support for MMDC profiling

Browse source

Add support for an extra config parameter for perf commands:
axi_id, which will be written in the MMDC's MADPCR1 register,
to filter memory usage profiling (see i.MX6 reference manual,
chapter 44.7 MMDC Profiling for AXI id usage).
