Felipe, all my changes are for this problem, these are fix build error and
let it work.

 As we change the connection-id, we need to change clock file or
 the devm_clk_get will be failed.

 We need to differentiate SoCs, so I use platform_device_id to
 instead of cpu_ix_xxx(), this is for machine file change

 Need to get platform_device_id at driver, and replace the cpu_is_xxx to
 platform_device_id. Meanwhile, needs a solution for replace
 MX35_IO_ADDRESS.

I can split this patch to two patches, one is driver part, the other is
machine part. It can also fix build break, but it needs two
patches to let the udc work.
