Document the steps required to flash the barebox image to a QSPI NOR
flash. This can be helpful if the user-space wants to update the QSPI
NOR barebox image. These steps can be skipped if barebox is updated by
the qspi bbu-handler.

The barebox i.MX images have a preamble that pads the i.MX header to
the offset expected by the BootROM. This allows writing barebox images
directly to offset 0 on SD-Cards and eMMC user area. For some i.MX8M,
these images can't be directly written to eMMC boot partitions and
instead require special handling. Add a note about this to the
documentation.

With i.MX8MP A1 silicon the OCRAM space is extended to 576KB whereas
the pre-release silicon has only 512KB. So the upstream TF-A adapted the
base address to move BL31 to the last 128KB of the OCRAM.
The adaption was a bit messy because each version changed it:
- v2.4 base addr = 0x960000 (original)
- v2.5 base addr = 0x970000 (adapted to new silicon revision)
- v2.6 base addr = 0x960000 (changed back by accident)
- v2.7 base addr = 0x970000 (accident fixed)
With v2.7 it is correctly set for A1 silicon onwards and we strongly
recommend to use this version or newer.
This commit also adapts the documentation for the i.MX8MP-EVK to
reference the upstream TF-A and to point out our favorite version.

This adds support for the NXP i.MX8MP-EVK board.
The SDRAM timings are taken from U-Boot-2020.07-rc4, other information
how to initialize the board are form U-Boot as well.
