It's the second posting of the patches adding I2C driver for ZTE ZX2967
family SoCs.  Thanks a lot for Wolfram's review comments on v1 patch,
which helps identify issues with NACK handling.

Changes for v2:
 - Add COMPILE_TEST for Kconfig option dependency.
 - Drop warning message for unsupported SMBus transfer, since the driver
   will fall back to emulate them via I2C anyway.
 - Kill ZX2967_I2C_FUNCS define by returning I2C_FUNC_XXX directly.
 - Drop error message for i2c_add_numbered_adapter() check, since the
   core will do the reporting.
 - Drop the error checking from zx2967_i2c_reset_hardware() which is
   useless now, and add it into irq handler for proper NACK handling.
