Pin to the latest stable 5.10.18 release in order to ensure patches
don't unexpectedly conflict in newer linux versions.
The wi-fi firmware has since been upstreamed to the `linux-firmware`
repo, and as such is now available via `enableRedistributableFirmware`.
As a result we can remove the old expr that pulled the firmware from
kvalo's github.
Also removes two patches that have since been upstreamed.
Removes the old disable-mhi-2 patch file in favour of using the patch at
kernel.org.
Also adds fwupd to allow users to update their firmware via fwupdmgr.
Disabling the MHI M2 state appears to completely resolve issues where
enabling the wifi firmware would cause the the whole system to freeze
quite frequently. The reason for why this fix works so well is still
unknown and under investigation. See some discussion here:
http://lists.infradead.org/pipermail/ath11k/2020-December/000876.html
Also renames the firmware package to clarify that it is for the wifi
driver. This is to avoid confusion with the bluetooth firmware which
will be added in an upcoming patch.
Here's a link to kvalo's branch with the kernel patches:

The patches are based on version 5.10-rc4 of linux, so you'll want to
use `linuxPackages_testing`.
trace: warning: The option `i18n.consoleFont' defined in
`/nix/var/nix/profiles/per-user/root/channels/nixos-hardware/dell/xps/13-9360'
has been renamed to `console.font'.
1 default one, with nvidia working and intel working, needs optirun to
run application with nvidia
2 intel only, I am using this as my daily driver for long time, only
intel is turned on and nvidia is turned off and doesn't drain any
power.
3 nvidia only, intel is dissabled and nvidia is picked as default gpu,
no need to fiddle with optirun etc, good for gpu heavy application.
All these settings needs to reboot to work properly
