Drop macbook12-spi-driver-dkms, which no longer builds on 7.x kernels

[karlentwistle]

install/hardware/apple/fix-spi-keyboard.sh installs macbook12-spi-driver-dkms on SPI-keyboard MacBooks, but the package no longer builds against 7.x kernels (linux-omarchy is 7.2.3). On 7.2.3 the DKMS build fails whenever headers are installed or the kernel updates:

apple-ib-als.c:679:19: error: initialization of 'void (*)(struct platform_device *)' from incompatible pointer type 'int (*)(struct platform_device *)'
apple-ibridge.c:901:10: error: 'struct acpi_driver' has no member named 'owner'
==> WARNING: `dkms install --no-depmod macbook12-spi-driver/0+git.315 -k 7.2.3-arch1-3' exited 10

The keyboard and trackpad don't depend on it: applespi has been in mainline since 5.3, and it's what gets loaded (/lib/modules/7.2.3-arch1-3/kernel/drivers/input/keyboard/applespi.ko.zst). The mkinitcpio MODULES drop-in only names in-tree modules, so it stays as it is.

Changes:

• Stop installing the package in fix-spi-keyboard.sh
• Remove it from omarchy-other.packages
• Add a migration that drops it from existing installs

Tested on a MacBook9,1 (Omarchy 4.0.3, kernel 7.2.3-arch1-3): removed the package, the UKI rebuilt cleanly, and after a reboot the keyboard works at the LUKS prompt and in the session. The migration no-ops when the package is absent. ./test/cli and test/shell.d/t2-hardware-test.sh (which reads omarchy-other.packages) pass.

One note for the 2016–17 Touch Bar MacBook Pros (MacBookPro13,2/13,3/14,2/14,3): the Touch Bar and ambient light sensor drivers came from this package. They already fail to build, so removing it doesn't take anything away that currently works, but I haven't been able to test on those models.

Sounds like it should be forked, fixed, and the upstreamed stuff removed.
