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));

089b1c17f6 driver/sensor: add fetch api to read sensor data directly
1.use userspace buffer rather than intermediate buffer of upperhalf driver
2.support block and non-block ways.
