Subject: [PATCH] zmx25: Fix build warning due to 'get_reset_cause' defined but
not used
When building the zmx25 target we get:
Configuring for zmx25 board...
generic.c:108: warning: 'get_reset_cause' defined but not used
Fix this warning by defining get_reset_cause only if CONFIG_DISPLAY_CPUINFO is defined.
