Subject: [PATCH] nvme-apple: Add "apple,t8103-nvme-ans2" as compatible

After discussion with the devicetree maintainers we agreed to not extend
lists with the generic compatible "apple,nvme-ans2" anymore [1]. Add
"apple,t8103-nvme-ans2" as fallback compatible as it is the SoC the
driver and bindings were written for.

This is split off from the v1 series adding Apple M2 Pro/Max/Ultra
device trees in [2]. Handling this as fix adding a device id only for
v6.18+ for two reasons. apple_nvme_of_match gained hw_data in v6.18 and
device trees using this compatible were only added in v6.18.

Changes compared to the patch in that series:
- rebased onto v6.19-rc1 since commit 04d8ecf37b5e ("nvme: apple: Add
  Apple A11 support") introduced hw data for the match table
