[PATCH v2] ACPI: Enable CONFIG_ACPI_DEBUG by default

[PATCH v2] ACPI: Enable CONFIG_ACPI_DEBUG by default

[Mario Limonciello]

From: Mario Limonciello <mario.limonciello@amd.com>

CONFIG_ACPI_DEBUG can be helpful for getting debug messages on OEM
systems to identify a BIOS bug.  It's a relatively small size increase
to turn it on by default (50kb) and that saves asking people to enable
it when an issue comes up because it wasn't in defconfig.

Enable it by default.

  * Fedora, Ubuntu, and CachyOS are all doing this in their distro kernels
    and haven't had any complaints about it.
