[U-Boot] [PATCH v2] zmx25: Fix build warning due to 'get_reset_cause' defined but not used

[Fabio Estevam]

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.

Changes since v1:

- Only define get_reset_cause when CONFIG_DISPLAY_CPUINFO is defined.
