i2c: Add Qualcomm CCI I2C driver

This commit adds I2C bus support for the Camera Control Interface
(CCI) I2C controller found on the Qualcomm SoC processors. This I2C
controller supports two masters and they are registered to the core.

CCI versions supported in the driver are msm8916, msm8996 and sdm845.

This is a rework of the patch posted by Vinod:
https://patchwork.kernel.org/patch/10569961/

With additional fixes + most of the comments addressed.

If you say yes to this option, support will be included for the
built-in camera control interface on the Qualcomm SoCs.
This driver can also be built as a module. If so, the module
will be called i2c-qcom-cci.
