Ungating all clocks won't have functional problem, but consume more power at booting. For mx6 platforms,
we won't change it any more, but on following mx7, we will use a new function to initialize needed clocks.

I think the DCD script "imximage.cfg" is not conflict with SPL. Because for non-SPL case, this file is needed. They are not exclusive.
At default Freescale release, we use DCD and plugin. But actually, DCD, SPL and plugin can exist with each others. This provides
options for customer to choose.
As a initial BSP version, we only support DCD here, neither SPL and Plugin. But we could consider to add in future.

The i2c_probe is needed only call once. Since it is a light weight encapsulation for using pca953x, I don't want
to add more variables nor functions. I will remove the i2c_probe in next version, it is not necessary.
