plat: imx8mp: change the bl31 physical load address

on i.MX8MP A1 silicon, the OCRAM space is extended to 512K + 64K,
currently, OCRAM @0x960000-0x980000 is reserved for BL31, it will
leave the last 64KB in non-continuous space. To provide a continuous
384KB + 64KB space for generic use, so move the BL31 space to
0x970000-0x990000 range.
