ENGR00308382-1 mcc: add a9 linux mcc_demo driver

- based on sema4 driver, mcc stack, add the mcc_demo driver
by sysfs.
  - mcc pingpong demo
  - mcc can demo
NOTE:
- rdc should be disabled in m4 mqx side, otherwise, a9 linux would
fail to mount rootfs.
- add the m4 related clks at linux side, because that the m4's clks
would be turned off/on during linux boot up if they are not added
at linux clk definitions.
