To support CMDQ secure driver, move some reuseable definition to header.
- define: e.g. CMDQ_GCE_NUM_MAX, CMDQ_THR_BASE, CMDQ_THR_SIZE.
- struct: e.g. cmdq_thread, cmdq, cmdq_task.
- include: e.g. <linux/clk.h>.
Add "#include <linux/mailbox_controller.h>" for the function that takes
"struct mbox_chan * chan" as a parameter. That may occur a build error
if secure driver header includes the mtk-cmdq-mailbox.h.
- function: e.g. cmdq_get_shift_pa(struct mbox_chan *chan).
