event/dpaa: fix integer overflow of max ports

dev_info->max_event_ports is uint8_t. dpaa_event_dev_info_get assigns
DPAA_EVENT_MAX_EVENT_PORT (which is RTE_MAX_LCORE, upto 256 in ppc64le)
into this variable, which breaks compile in ppc64le.

drivers/event/dpaa/dpaa_eventdev.c: In function ‘dpaa_event_dev_info_get’:
   rte_config.h:23:23: error:
   large integer implicitly truncated to unsigned type [-Werror=overflow]
      #define RTE_MAX_LCORE 256
