Commit "ARM: i.MX IOMUX-V3 replace struct pad_desc with bitmapped cookie"
(b705cb4d42e95a4a43a8945571c8613e71526c3d) introduced a typo which was
preventing my efikamx to boot. This patch is fixing that.

The following patch is a first step to convert the 'struct pad_desc'
to a bitmapped cookie to facilitate adding platform specific pullup or
drive strength definitions to existing pad definitions without need to
rewrite the complete pad def.

The patch wraps 'struct pad_desc' in an opaque data type and
introduces macros to access the individual members.
This patch does not constitute any functional change!

The current model does not allow to put a pad into different modes
once a pins is allocated. Remove the resource handling.

also, check for a valid pad_ctrl_ofs before changing the
pad control register.

This iomux is called iomux-v3 in the tree because it is the third known
incarnation of MXC iomuxers. It is not only found on the MX35 but also
on the MX51 and probably others.
