This patch adds support for Two-Wire interface in AVR Dx chips.
Only master mode is supported in this version.
The driver was tested using TC74Ax thermal sensor and simple application
that read the temperature from it. (Driver for the sensor is not in-tree.)

Add complete driver support for the QST QMI8658 6-axis IMU sensor featuring
3-axis accelerometer and 3-axis gyroscope with I2C interface and uORB
integration.
Key features implemented:
* Full I2C communication with configurable frequency (default 400kHz)
* Multiple accelerometer ranges (±2g, ±4g, ±8g, ±16g) and ODR settings
* Multiple gyroscope ranges (±16 to ±1024 dps) with high ODR support
* Low-pass filter configuration for both sensors
* Temperature sensing with 16-bit resolution
* Self-test capability for both accelerometer and gyroscope
* Calibration-on-demand support with offset registers
* FIFO buffer management (framework ready)
* Interrupt-driven and polling mode support
* Complete uORB integration with sensor_accel and sensor_gyro topics
Driver components added:
* Core driver implementation (qmi8658_uorb.c) with register operations
* Header file with register definitions and scale factors (qmi8658.h)
* Kconfig options for driver configuration and polling mode
* Build system integration (CMakeLists.txt, Make.defs)
* Comprehensive documentation with API reference and usage examples
The driver follows NuttX sensor framework conventions and provides
robust error handling, mutex protection, and comprehensive debugging
support through CONFIG_DEBUG_SENSORS.

This adds ability for read and write operations to work with messages
aligned to configured number of bytes. This has few different use
cases.
The alignment is specified as unsigned integer and can be changed with
ioctl command CANIOC_SET_MSGALIGN. The current value can be queried by
CANIOC_GET_MSGALIGN command.
The default value for the message alignment is 1. This will provide
behavior consistent with current one. Thus messages are placed to the
buffer right after data of the previous one. The same applies for
writes.
The special alignment value 0 disables read and write of multiple frames. Thus
read will always return at most one message and write will always write
only one message even if larger buffer size is provided.
Another use case is if message alignment is set to exactly message
representation size (`sizeof(struct can_msg_s)`). This allows writing
and reading arrays of messages.
Other values provide even more advanced and specialized use cases, such
as optimizations if architecture has to emulate some non-aligned
accesses, there alignment of for example 4 bytes could provide
performance boost.
The original motivation behind this is was compatibility with socket
CAN. It is easier to port applications to NuttX's CAN driver if only one
frame is provided at the time. This solution was suggested by Pavel Pisa
<pisa@fel.cvut.cz> as a more versatile variant of plain boolean
disabling the multiple frame retrieval.
