[FR] Support Raspberry Pi OS 64-bit (beta version)

https://www.raspberrypi.org/forums/viewtopic.php?t=275370

This is a beta test of the Raspberry Pi OS (64 bit)

We still recommend the 32 bit operating system for all Pis at this time, although have decided it is now time to begin the move toward a 64bit OS. For the moment this is a 'beta' program, the OS is in heavy flux and its functionality is likely to change significantly over the next few months.

Note, the 64bit OS is only install-able on the Pi 3 and Pi 4 devices

Latest 64-bit image: https://downloads.raspberrypi.org/raspios_arm64/images/

It seems 64-bit image needs to be rebased to Debian Buster 10.7 rathernn than 10.5
I have the following error when apt update/upgrade.
