Tim Lin 648919f6df drivers/i2c: it51xxx: Refactor ISR to reduce clock stretch in PIO mode
Move handling of write-to-clear status and stop detect to the
beginning of the ISR for PIO mode to reduce unnecessary clock
stretching and improve responsiveness during transfers.

This patch also separates status clearing for shared FIFO mode,
ensuring it is done at the appropriate point after data handling
completes, maintaining correct transfer behavior.

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, Tensilica Xtensa, and RISC-V,
SPARC, MIPS, and a large number of `supported boards`_.
