[PATCH v2 0/1][SRU][X/B/F/G/H linux-aws] UBUNTU: [Config] Disable Atari partition support

[Heitor Alves de Siqueira]

BugLink: https://bugs.launchpad.net/bugs/1908264

[Impact]
Atari partition tables have very broad specifications, and can
spontaneously show up on uncleared disks with "garbage" data. There have
been reports of misinterpreted AHDI partition tables before (see [0] and
[1]), usually as an unintended side-effect of using non-zeroed disks.
Users of this specific partition scheme are unlikely to be on AWS
instances, so we should disable them.

[1] https://mail-index.netbsd.org/port-atari/1995/11/19/0001.html

[Test Case]
Ensure that CONFIG_ATARI_PARTITION is not set in /boot/config-$(uname -r)

[Fix]
Unset CONFIG_ATARI_PARTITION in debian.aws/config/config.common.ubuntu

[Regression Potential]
There could be unexpected dependencies on Atari partitions that are
impacted by this change. Considering Atari hardware hasn't been produced
in a long time, and is unlikely to be used in AWS instances, the
regression potential should be very low.
