Update Basic Setup with new t2bce modules

[h0m3]

The old apple-bce module was replaced by the new modular t2bce_audio, t2bce_vhci, t2bce_core and t2bce_dma but the wiki still points to apple-bce on wiki.t2linux.org/guides/postinstall which doesnt exists anymore and breaks the creation of the initramfs image if you set to load early.

The wiki need to update to reflect the new module names.

mkinitcpio.conf example:

MODULES=(
    t2bce_core
    t2bce_dma
    t2bce_vhci
)

In my case thats necessary due to my early password prompt for the LUKS disk encryption.

I couldn't update due to personal commitments. You may open a PR if you want it done sooner.
