[Nouveau] [PATCH resend] drm/nouveau: fix acpi related kbuild warnings

Currently when X86 && ACPI && !X86_PLATFORM_DEVICES kbuild spits:
warning: (DRM_NOUVEAU) selects ACPI_WMI which has unmet direct
dependencies (X86 && X86_PLATFORM_DEVICES && ACPI)
warning: (DRM_NOUVEAU) selects MXM_WMI which has unmet direct
dependencies (X86 && X86_PLATFORM_DEVICES && ACPI_WMI)
and goes on, which leaves a situation where ACPI_WMI (which depends on
X86_PLATFORM_DEVICES) is enabled but X86_PLATFORM_DEVICES is not.
Additionally, Nouveau on IA64 would enable these X86-related drivers
when ACPI is enabled (doesn't matter but is wrong) and build
nouveau_acpi.c which depends on them.
To fix this, introduce hidden DRM_NOUVEAU_ACPI variable which selects
all acpi/x86 related configs and select it when both X86 and ACPI are
enabled.
