Phase I (a): redbear-quirks enrichment. Each flag is ported from the Linux 7.1 reference tree and applied to LG Gram 16 (2025) 16Z90TR and 16T90SP (2026 Panther Lake). The flags are generic and applicable to other OEMs too: * acpi_irq1_skip_override — Linux drivers/acpi/resource.c irq1_level_low_skip_override[] (lines 522-534). Without this the ACPI core rewrites the DSDT's ActiveLow to ActiveHigh and the i8042 keyboard IRQ stops firing on LG Gram. * kbd_deactivate_fixup — Linux drivers/input/keyboard/atkbd.c line 1913-1917. Prevents spurious keyboard ACK / dropped keys on LG hardware. * no_legacy_pm1b — Red Bear OS specific. LG firmware does not implement a separate PM1b_CNT register; tells acpid to skip the SLP_TYPb write path. Also adds a 17U70P entry (Linux matches this on board_name) and a catch-all LG Electronics entry (Linux atkbd.c matches on sys_vendor only, not product_name). Hardware-agnostic: the same flags apply to Dell, HP, Lenovo laptops with similar firmware quirks. Future Phase I work will add DMI matches for those vendors based on the Linux quirk tables. Also updates local/sources/kernel submodule pointer to 7a38664 (Phase I [patch.crates-io] for redox_syscall).
