[PATCH 0/2] Apple T2 platform support

[Hector Martin]

Hi all,

This short series adds the missing bits to support Apple T2 platforms.

There are two quirks: these devices have firmware that requires the
host to provide a blob of randomness as a seed (presumably because the
chipsets lack a proper RNG), and the module/antenna information that
is used for Apple firmware selection and comes from the Device Tree
on ARM64 systems (already upstream) needs to come from ACPI on these
instead.

Changes since the megaseries from a ~year ago: made the ACPI code bail
if there is no module-instance, so we don't try to get the antenna
info at all in that case (as suggested by Arend). Made the randomness
conditional on an Apple OTP being present, since it's not known to be
needed on non-Apple firmware.
