[PATCH] drm/nouveau: Fix Kconfig issue with CONFIG_ACPI_WMI

[Armin Wolf]

Nouveau uses wmi_evaluate_method() when CONFIG_ACPI_WMI has been
enabled, but this alone does not guarantee that CONFIG_ACPI_WMI
is actually reachable. If CONFIG_ACPI_WMI is m and CONFIG_DRM_NOUVEAU
is y, said function will not be reachable by nouveau, resulting in
a linker error.

Until now this issue was not triggered because on x86
CONFIG_ACPI_WMI is automatically selected by nouveau. However the
ACPI-WMI subsystem has added support for other ACPI-compatible
architectures like Risc V, making it possible for users to trigger
this bug.

Fix this by always selecting ACPI_WMI if ACPI support is enabled
to ensure that nouveau can actually reach wmi_evaluate_method().
