Since the last Raspberry Pi 5 submission has no progress, I'm submitting
these patches anyway. The newly released Raspberry Pi 5 board shares
similar software structure except it has less proprietary API.
Therefore, rpi-userland and all of raspberry-centric GPIO utilities are
no longer supported.

Keep in mind that RPi 5 has no native 32-bit support due to Cortex-A76
processor specification. That is the reason why I did not add _64.

Changes v1 -> v2:
  - Fix missing newlines due to terminal issue

Changes v3 -> v4:
  - Rebase to master
  - Drop 4K page size, until we figured out how to run 32bit userspace
    on top of 64bit kernel
  - Change back from commit ID to commit tag
  - Rewrite the commit description
  - Fix incorrect CPU from upstream config, RPi5 has no LITTLE.big

Thanks, but here you're submitted a diff against the previous
raspberrypi5_defconfig submission. Please submit a full patch adding
the complete support for RPi5, not a diff against some random other
patch posted on the mailing list.

Thanks!

Thomas
