Subject: nouveau_pm.c: Build error

In nouveau_pm.c, in the function nouveau_pm_acpi_event(), there's no
check for CONFIG_POWER_SUPPLY.

If CONFIG_POWER_SUPPLY is set to either n or m, the
power_supply_is_system_supplied() is 'missing' and there's a build error.

One solution is to add an #ifdef CONFIG_POWER_SUPPLY along with the
#ifdef CONFIG_ACPI before the function.
