Description

### Pre-flight checklist

- [x] I have searched existing issues and this is not a duplicate.
- [x] I have read the [Contributing Guidelines](https://github.com/CachyOS/linux-cachyos/blob/master/CONTRIBUTING.md).
- [x] I have verified the issue is reproducible with the latest available CachyOS kernel.
- [x] I have tried to reproduce the issue on Arch Linux's `linux` kernel.

### Upstream / vanilla kernel check

I tested with a vanilla/upstream kernel and the issue does NOT reproduce there (CachyOS-specific bug)

### Kernel variant

linux-cachyos (EEVDF, Clang)

### System information (cachyos-bugreport.sh)

### Bug description

Kernel 7.2 caused an OS installation regression when installing from a live ISO on T2 Macs. `apple_bce` is no longer available in kernel 7.2, which has migrated to `t2bce_dma`, `t2bce_core`, and `t2bce_vhci`.

https://github.com/CachyOS/chwd/blob/master/profiles/pci/t2-macbook/profiles.toml needs to be updated because `chwd` failure aborted the installation.

### Steps to reproduce

Install CachyOS from a live ISO on a T2 Mac.

### Expected behavior

The installation should pass. Or we should have an option to install LTS kernel only, or skip `chwd` during installation.

### Actual behavior

`chwd` broke the installation due to kernel 7.2 does not ship `apple_bce` anymore
