Subject: [PATCH] tc1100-wmi: fix build warning when CONFIG_PM not enabled

From: Colin Ian King <colin.king@...onical.com>

Conditionally declare suspend_data on CONFIG_PM to avoid
the following warning when CONFIG_OM is not enabled:

drivers/platform/x86/tc1100-wmi.c:55:27: warning:
  'suspend_data' defined but not used [-Wunused-variable]
