Added Modules so the Surface Laptop 5 built-in Keyboard Works at Login

[gaudi369]

On my Surface Laptop 5, the built-in keyboard doesn’t work at the login screen, but it starts working normally after logging in. I added some modules to '/etc/mkinitcpio.conf' and it fixed the issue for me. I also found a few people on the Omarchy Discord reporting the same issue, so this seems reproducible on other Surface 5 systems.

Steps to reproduce the original problem:
1. Boot Omarchy on a Surface Laptop 5.
2. At the password login screen, the keyboard doesn’t respond.
3. After logging in (using an external keyboard), the built-in keyboard works normally.

Here’s the module list that worked for my setup:

MODULES=(btrfs crc-itu-t usbhid hid-generic pinctrl_tigerlake intel_lpss_pci
8250_dw surface_gpe surface_hotplug surface_aggregator_registry
surface_aggregator_hub surface_aggregator surface_hid_core surface_hid
surface_kbd xhci_hcd hid_multitouch)

After looking through the Omarchy repository, I noticed there’s a similar hardware-specific fix for MacBook SPI keyboards. I used that script as a reference and, with some AI assistance, created a matching patch for the Surface Laptop 5.

The patch is implemented as:

omarchy/install/config/hardware/fix-surface5-keyboard.sh

It mirrors the style of fix-apple-spi-keyboard.sh and just writes a mkinitcpio drop-in file.

This fix may require surface-linux kernel installed too.

@gaudi369 are you able to test without the surface-linux kernel to see if that's something that is actually required or not?

Outside of that, this looks generally fine but if we also have to handle that kernel, that changes things a bit.
