MLK-12182 ARM: imx: add M4 ddr image DSM support on i.MX7D For DSM mode, M4 TCM context is lost and A7 will restore them after resume and write TCM entry to M4 and re-kick it. It assumes M4 is running on TCM, but M4 also has case of running image on DDR, OCRAMS first 2 words stores the stack and pc address for M4, to support M4 running on both TCM and DDR case, we can just leave the OCRAMS first 3 words unchanged during DSM, the third words is also reserved for M4, as OCRAMS can keep its context during DSM. This patch leaves OCRAMS first 3 words unchanged and remove the re-program of TCM entry after exit from DSM, thus it can support DSM mode for M4 running on TCM/DDR/OCRAM.
