drivers: imx_i2c: add I2C support

This driver provides native access to the I2C bus on iMX.

The driver will not query the clock hierarchy - to find the base clock
rate - because it overcomplicates the deliverable for not much added
value (this can be done at a later time if required).

The U-Boot and Linux GPL code was initially used as a reference;
however due to the simpler OP-TEE use case requirements, the code was
later re-written following the reference manual [1].

This driver will not access addresses within a I2C slave map.

This driver must not be used while the Linux kernel is running unless
the following is guaranteed:
- that the I2C bus will not be suspended.
- that there will not be collisions with other bus masters.

Without those guarantees, please use a trampoline driver to route the
I2C requests to Linux.

Tested on imx8mm-lpddr4.
