Eero Nurkkala 1d3ce6b527 arm64/imx9: provide EL3 bootloader support for iMX9
This provides a capable bootloader that may be run from OCRAM.
The OCRAM contains regions that are always zero, so the linker
file avoids those with best effort.

iMX9 infrastructure expects:
  - 0x20480000 (Start of OCRAM, AHAB)
  - 0x2049a000 (NuttX or SPL)
  - 0x204e0000 (ARM Trustzone, not used)

When started from SD-card, the offsets are:
  - 0x1f000 with AHAB
  - 0xa000  without AHAB
