[PATCH v3 0/2] Add Apple T2 NHI device links

[Atharva Tiwari <atharvatiwarilinuxdev@gmail.com>]

This series adds a cached flag to detect Apple T2 systems, then uses it
to create device links for the Thunderbolt NHI.

Changes in v3:
- Fix build errors with non-x86 machines
- Used __initconst for apple_t2_devices
- Removed UEFI_QUIRK_SKIP_CERT as its unused now
- Used IS_ENABLED(CONFIG_ACPI) in tb_apple_add_links for the T2 part
- Removed !bid check to remove warning with -Waddress

Changes in v2:
- Used a less generic name for has_t2_chip
- Used DMI instead of PCI for has_apple_t2_chip to avoid PCI problems
- Initialized ret in tb_apple_add_links
