Agree. Please correct me if I am wrong, but with these changes we should
sure that the iomux register are not set if we do not want, because in
imx_iomux_v3_setup_pad:

if (sel_input_ofs)
	__raw_writel(sel_input, base + sel_input_ofs);

and NO_MUX_I = 0 should set sel_input_ofs to 0.

It is then difficult to understand why we have up now 0x3FF as value,
but it neverminds..

(This is a fix, I will merge it for the release)
