[PULL,04/41] hw/arm: Restrict APEI tables generation to the 'virt' machine

From: Philippe Mathieu-Daudé <[e-mail]>

While APEI is a generic ACPI feature (usable by X86 and ARM64), only
the 'virt' machine uses it, by enabling the RAS Virtualization. See
commit 2afa8c8519: "hw/arm/virt: Introduce a RAS machine option").

Restrict the APEI tables generation code to the single user: the virt
machine. If another machine wants to use it, it simply has to 'select
ACPI_APEI' in its Kconfig.

Fixes: aa16508f1d ("ACPI: Build related register address fields via hardware error fw_cfg blob")
