drm/nouveau: make vga_switcheroo code depend on VGA_SWITCHEROO
Commit 8116188fdef594 ("nouveau/acpi: hook up to the MXM method for mux switching.") broke the build on non-x86 architectures due to the new dependency on MXM and MXM being an x86 platform driver. It built previously since the vga switcheroo registration routines were zereod out on !X86. The code was built in but unused. This patch makes all of the DSM code depend on CONFIG_VGA_SWITCHEROO, allowing it to build on non-x86 and shrinking the module size as well.
