This PR has resolved the WiFi instability issues on my X1C purchased in February 2024. Before WiFi would crash and disable the menu option. |

We build in a new kernel that doesn't have any wireless support at all (otherwise, we crash with the backport!), and instead use the brcmfmac backport from 5.15.81-1, aiming it at the new WiFi firmware from #84. Even Murata says nobody should be using bcmdhd anymore, and so we do not either!

Murata have a newer version of the firmware for Infineon / Cypress / Broadcom BCM43430, which at least one user reports meaningfully improves WiFi stability on his printer. Override the base firmware's 7.45.96.76 (2020-12-21) with 7.45.98.125 (2022-08-16), and also include a new regulatory matrix bundle.
