LFU-278-18 imx: spl_imx_romapi: Workaround loading to OCRAM ECC region

ROM API has a limitation that ROM valid access range does not
include the OCRAM ECC 64KB on i.MX8MP.
When loading image from nand, the spl_load_fit_image will handle
the page unaligned access. In worst case, it requires to read to
more 2 pages. For ATF on iMX8MP, it default address is 0x970000,
so it is highly possible to read data into OCRAM ECC region after
adding more 2 pages.

To handle the case, we use a temp buffer to replace the OCRAM ECC
region for ROM API. Then copy to OCRAM ECC region.
