rfkill should be disabled according to the Surface Pro 11's DSDT.
https://lore.kernel.org/all/20250113074810.29729-3-quic_lingbok@quicinc.com/
has added support to read the ACPI bitflag when ACPI is supported.
The idea was to expose one specific feature (DISABLE_RFKILL_BIT) for
devices described with a DT, so that the feature can be disabled.
