Ard Biesheuvel c647c00f28 acpi/arm64: ignore 5.1 FADTs that are reported as 5.0 
[ Upstream commit 2af22f3ec3 ]

Some Qualcomm Snapdragon based laptops built to run Microsoft Windows
are clearly ACPI 5.1 based, given that that is the first ACPI revision
that supports ARM, and introduced the FADT 'arm_boot_flags' field,
which has a non-zero field on those systems.

So in these cases, infer from the ARM boot flags that the FADT must be
5.1 or later, and treat it as 5.1.
