boards: arc: emsdp: fix secure config for emsdp_em7d_esp

emsdp_em7d_esp is a board with secure just like em_starterkit_em7d,
but the secure feature not configed in defconfig file. we need to add
below configs in emsdp_em7d_esp_defconfig files:
    CONFIG_ARC_HAS_SECURE=y
    CONFIG_TRUSTED_EXECUTION_SECURE=y
when secure feature enabled, we use secure timer for system tick, so
we need to add below macro for secure timer:
    #define  IRQ_SEC_TIMER0  20
