This driver implements `read`, `write`, `open`, `close` and `ioctl`
interfaces to the SHT4X temperature and humidity sensor on an I2C bus.
The read implementation is that of a character driver for easy
debugging, while `ioctl` provides an interface to the sensor's raw data
collection and heating functionality.

In order to obtain best accuracy over temperature range,
particularly in low temperature, it is recommended to
compensate the non-linearity over the temperature.

The BIT macro is widely used in NuttX,
and to achieve a unified strategy,
we have placed the implementation of the BIT macro
in bits.h to simplify code implementation.

convert from body coordinate system to right-hand
coordinate system.
Example:
Compared to the standard coordinate system,
the x-axis and y-axis are interchanged and have opposite directions,
the z-axis remains normal.
body coordinate ----> right-hand coordinate
+x +y
| |
| |
| |
| |
-y<-------. .------>+x
/ /
/ /
/ /
/ /
+z +z
So for the above conversion, using "P3" to represent transformation relationships
The front is 1 0 2, which represents the y x z axis.
The standard order is 0 1 2, so y and x are interchanged.
The following -1 1 1 indicates the direction of the axis.
The standard is 1 1 1. Because the current y-axis is opposite to
the standard x-axis, it is -1.
static const struct sensor_axis_map_s g_remap_tbl[] =
{
{ 0, 1, 2, 1, 1, 1 }, /* P0 */
{ 1, 0, 2, 1, -1, 1 }, /* P1 */
{ 0, 1, 2, -1, -1, 1 }, /* P2 */
{ 1, 0, 2, -1, 1, 1 }, /* P3 */
{ 0, 1, 2, -1, 1, -1 }, /* P4 */
{ 1, 0, 2, -1, -1, -1 }, /* P5 */
{ 0, 1, 2, 1, -1, -1 }, /* P6 */
{ 1, 0, 2, 1, 1, -1 }, /* P7 */
};
you can call the function sensor_remap_vector_raw16 and pass P3 parameters
to perform the conversion.

Solve the problem that when a user modifies the sampling rate,
the difference between the generation and the mainline generation
may be greater than the own sampling interval.
After this problem occurs, sensor_is_update() will continue to
return true, resulting in a busy loop in the upper-layer application,
so, need update user generation according to mainline generation.
