Subject: [PATCH] rtc: rtc-cmos: Fix compilation with CONFIG_ACPI unset

From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>

After commit 0782b66ed2fb ("rtc: rtc-cmos: Fix wake alarm breakage")
the driver won't build with CONFIG_ACPI unset due to a missing stub
definition of rtc_wake_setup(), so fix that.

Fixes: 0782b66ed2fb ("rtc: rtc-cmos: Fix wake alarm breakage")
