Tomasz Moń d034106b40 usb: device: cdc_acm: Warn once about full ring buffer
Generating separate log entry at INFO level for every single character
dropped is excessive and leads to log flood. Logging dropped character
in no way helps end user and is really a delayed performance killer that
triggers when CDC ACM buffer gets full.

If user does not want to lose outgoing characters then the solution is
to enable hardware flow control which properly blocks in the case the
output buffer is full.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM (Cortex-A,
Cortex-R, Cortex-M), Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V,
SPARC, MIPS, and a large number of `supported boards`_.
