[Impact]

 * There are lots of stylus couldn't be used on Lenovo's platform, our
OEM customer request to support ThinkPad P15 Gen 1, ThinkPad X1 Yoga
Gen5, ThinkPad P1 G3.

 * I reviewed and tested the below patches from upstream. It could
support the stylus very well on P15, P1 or X1 Yoga.

 * a864679 - Add multiple AES stylus definitions 
   I applied into libwacom2 1.3-2ubuntu1, no errors.

 * 8652aa3 - Add isdv4-aes stylus group to all AES sensors
  I tried to apply this patch, but there are not 'data/isdv4-48ca.tablet' and 'data/isdv4-48ce.tablet', it failed for these two files.

 * ba02abf - Add ISDv4 51e9 (Lenovo ThinkPad P15 Gen 1) (#325)

[Test Plan]

 * Need your laptop have AES stylus, check the pen setting at gnome-
control-center when the pen touch the screen. It could not set/customize
the stylus, such as the second button as right click.

 * After updated the new packages with these patches, you could
customize the stylus at gnome-control-center.

[Where problems could occur]

 * It only changes the data/ parts to support more stylus from upstream,
so it's low risk.
