bbswitch-dkms fails to build with jammy/linux-hwe-5.19

[Impact]
bbswitch-dkms fails to build with jammy/linux-hwe-5.19.

[Test case]

 $ sudo apt-get install bbswitch-dkms

[Fix]

To fix it we can take two approches:

a) we import the Lunar version (0.8-14) into Jammy, and it's missing dependency (dh-dkms)

or

b) we apply the attached debdiff that is syncing the Jammy version up to Lunar, reverting on top the bits depending on dh-dkms.

Whichever is the path of last resistance, i'm happy with it.

[Regression potential]

It's the same DKMS we are already using in Lunar, and it contains all the fixes upstream developed so far: Jammy and Lunar share the same base version (0.8).

uploaded changes into lunar to make it more backport friendly.

for jammy, i think i will upload cherrypick of linux-5.18 compat patch.

I couldn't test loading the module due to lack of hardware.

ADT tests were also successful with the GA 5.15 kernel:
