148afd9548 driver/sensors: support custom type of sensor.
For examples, the custom sensor could define:
struct custem_event_s
{
  uint64_t timestamp;
  int16_t adc[8];
};
struct sensor_lowerhalf_s g_lower =
{
 .buffer_size = 1024,
};
sensor_custom_register(lower, "/dev/sensor/custom0", sizeof(struct custem_event_s));
