Use CONFIG_IS_ENABLED() macro, which provides more convenient
way to check $(SPL)DM_I2C/$(SPL)DM_I2C_GPIO configs
for both SPL and U-Boot proper.
CONFIG_IS_ENABLED(DM_I2C) expands to:
- 1 if CONFIG_SPL_BUILD is undefined and CONFIG_DM_I2C is set to 'y',
- 1 if CONFIG_SPL_BUILD is defined and CONFIG_SPL_DM_I2C is set to 'y',
- 0 otherwise.
All occurences were replaced automatically using these bash cmds:
$ find . -type f -exec sed -i
's/ifndef CONFIG_DM_I2C/if !CONFIG_IS_ENABLED(DM_I2C)/g' {} +
$ find . -type f -exec sed -i
's/ifdef CONFIG_DM_I2C/if CONFIG_IS_ENABLED(DM_I2C)/g' {} +
$ find . -type f -exec sed -i
's/defined(CONFIG_DM_I2C)/CONFIG_IS_ENABLED(DM_I2C)/g' {} +
$ find . -type f -exec sed -i
's/ifndef CONFIG_DM_I2C_GPIO/if !CONFIG_IS_ENABLED(DM_I2C_GPIO)/g' {} +
$ find . -type f -exec sed -i
's/ifdef CONFIG_DM_I2C_GPIO/if CONFIG_IS_ENABLED(DM_I2C_GPIO)/g' {} +
$ find . -type f -exec sed -i
's/defined(CONFIG_DM_I2C_GPIO)/CONFIG_IS_ENABLED(DM_I2C_GPIO)/g' {} +
