arm/imx2x: removes a bunch of sparse-warnings

Here are some of the warnings that get fixed by this:

> 200 times: warning: cast adds address space to expression (<asn:2>)
twelve times: warning: symbol 'xxx' was not declared. Should it be static
two times: warning: symbol 'clock' shadows an earlier one
five times: warning: incorrect type in initializer (different address spaces)
