fix(suspend): load intel_lpss_pci from initramfs (Arch wiki touchpad fix)

Symptoms (Intel CPU + linux-hardened + blinking caps lock + hard
hang on resume from S3) are a direct match for the Arch wiki entry:

  https://wiki.archlinux.org/title/Power_management/Suspend_and_hibernate#Touchpad_causes_a_kernel_panic_on_resume
  https://bbs.archlinux.org/viewtopic.php?id=231881

When intel_lpss_pci is loaded late (via udev after userspace is up),
the touchpad/I2C controller it parents can be torn down by suspend
before the module's resume callback is registered, leading to a
NULL-deref panic during resume. The kernel never makes it far enough
to flush logs — which matches our 'PM: suspend entry (deep)' being
the last journal line.

Fix: load intel_lpss_pci from the initramfs so it's available before
the suspend/resume code path runs.

Why this only bites linux-hardened: the hardening config enables
INIT_ON_FREE, slab freelist hardening, page poisoning, and stricter
pointer validation, which turn what's a silent UAF on stock linux
into an immediate panic on hardened. Stock 'just works' by accident.

Also drop the speculative init_on_free=0 from the hardened cmdline
now that we have a targeted hypothesis. Keep nmi_watchdog=panic +
softlockup_panic=1 + panic=10 as belt-and-braces: if this fix is
wrong, the next hang will auto-reboot with a usable panic log in
'journalctl -b -1 -k' instead of needing the power button again.
