PC just makes line shorter, but it has no meaning. At least, change the
name with something related to I2C or do not use the macro. I think it
is more readable.

I have expected that PMIC is configured here. Which is the reason to
have power_init_board ? It looks like an empty function.

Is this ok ? You have surrounded the I2C initialization with
CONFIG_SYS_I2C_MXC, but port_exp_direction_output() is outside. What
happens if CONFIG_SYS_I2C_MXC is not set ? Anyway, if you think that
CONFIG_SYS_I2C_MXC must be set, you could drop the #ifdef.

No comment, but I am gently asking if you have thought to switch to
distro environment. It makes board behaving in the same way.
