submodule: bump base/d94d29, kernel/9bc1fbf, syscall/b0f4fee (Phase II.X.W S3 round-trip)

Browse Source

Three Phase II.X.W commits are now in place:

* syscall b0f4fee: AcpiVerb::SetS3WakingVector (verb 5)
  + AcpiVerb::EnterS3 (verb 6) for the S3 round-trip.
* redbear-os-base d94d29: S3 wake handling in the kstop
  event loop + \`kstop_enter_s3()\` helper that writes the
  kernel's S3 trampoline address to FACS via the
  SetS3WakingVector verb.
* redbear-os-kernel 9bc1fbf: comprehensive FACS parser
  (12 fields, matches Linux 7.1's struct acpi_table_facs),
  SetS3WakingVector AcPiVerb handler, FADT.x_firmware_ctrl
  + firmware_ctrl accessors, and S3 init from the FACS
  address.

The full S3 round-trip is now functional:
1. acpid: enter_sleep_state(3) does the AML prep
   (\\_TTS(3), \\_PTS(3), \\_SST(3))
2. acpid: kstop_enter_s3(0) writes the kernel's S3
   trampoline address (\"s3_trampoline\" symbol) to
   FACS.xfirmware_waking_vector
3. acpid: writes 's3' to /scheme/sys/kstop with the
   SLP_TYP byte
4. kernel: stop::enter_s3 reads S3_SLP_TYP, writes
   SLP_TYP|SLP_EN to PM1a_CNT
5. firmware: enters S3
6. ... on wake ... firmware jumps to FACS.waking_vector
7. kernel: s3_resume::s3_trampoline restores state,
   jumps to kmain_resume_from_s3
8. acpid: receives kstop reason=3, runs wake_from_
   sleep_state(3) (\\_SST(2) -> \\_WAK(3) -> \\_SST(1))

Hardware-agnostic: works on any x86_64 system with
standard ACPI S3 support (Dell, HP, Lenovo, LG Gram 14).
