Regenerate P2 patches against current upstream (463f76b9 + redox.patch)

Browse Source 
Both P2 patches were stale — generated against an older upstream HEAD whose
context lines shifted after redox.patch modified the same files. Regenerated
from scratch against the current upstream commit so they apply cleanly.

P2-boot-runtime-fixes: hwd I2C candidate logging, pcid-spawner initfs detach,
pcid sendfd PCI fd handoff (319 lines)
P2-acpi-i2c-resources: new acpi-resource shared decoder crate (688 lines),
acpid /scheme/acpi/resources/ endpoint, resources.rs re-export shim,
sleep.rs restore (1265 lines)
