Hi, Fabio,

Changes since v1:
- iomuxc was accessed directly in v1, so create a iomux struct
so that we can use io accessors

I think iomux register does not limited to the above registers and you defined some unused register such as IOMUXC_OBSERVE_MUX_0, if you only use gpr, you can just define iomuxc_gpr etc.
And what's more, mx51 and mx53 has different layout, on i.mx51, the layout is:
IOMUXC_GPR0, IOMUXC_GPR1, IOMUXC_OBSERVE_MUX_0, IOMUXC_OBSERVE_MUX_1, IOMUXC_OBSERVE_MUX_2, IOMUXC_OBSERVE_MUX_3,
so, you can't simply put it to the common head file for all the i.mx5 soc.
