[Philip Paeps]

This makes mxc_iomux_set_input() work as expected.

[U-Boot] [PATCH v2] mx35 iomux: correct offsets of IOMUX registers

[Philip Paeps]

This makes mxc_iomux_set_input() work correctly.  Previously, the
incorrect offset of IOMUXSW_INPUT_CTL caused mxc_iomux_set_input()
to write to the wrong register, possibly resulting in unexpected
behaviour.

Changes in v2:
 - While here, also correct the offset of the last pad control
   register.  This is mostly cosmetic.

You're right, offset were wrong.
