Comment 2 for bug 2042710

This is the relevant dracut commit for spi_pxa2xx_platform: https://github.com/dracutdevs/dracut/commit/df381b7e0cd95f78e40ac70f0f3c96a2fa8dd189

```
$ modprobe --show-depends spi_pxa2xx_platform
insmod /lib/modules/6.5.0-10-generic/kernel/drivers/dma/dw/dw_dmac_core.ko.zst
insmod /lib/modules/6.5.0-10-generic/kernel/drivers/dma/dw/dw_dmac.ko.zst
insmod /lib/modules/6.5.0-10-generic/kernel/drivers/spi/spi-pxa2xx-platform.ko.zst
```

intel_lpss_pci or mfd (from mfd/intel_lpss_pci path) are not directly mentioned in dracut. Neither does `dracut_instmods -o -s "${_blockfuncs}" "=drivers"` install intel_lpss_pci.

dracut does not seem to install intel_lpss_pci:

```
$ schroot-wrapper -p dracut,linux-image-generic,systemd-sysv -c mantic -u root
[...]
(mantic)root@host:~# lsinitrd /boot/initrd.img-6.5.0-10-generic | grep intel_lpss_pci
(mantic)root@host:~#
```
