drivers: i2c: Base OMAP I2C support for TI-K3 processor

The OMAP I2C provides support for I2C serial interface on TI K3 series.
It is compatible with Philips I2C physical layer.
The commit includes:
Zephyr i2c api implementation
Bus Recovery

Bus recovery feature utilizing bit-bang operations, which sends 9 SCL clock
pulses to recover the bus and checks if the line is down. Upon recovery,
it disables the system test register before resuming the transactions.
