Originally this patch came form TI and not sure that they are using the 
both cable detection or only single type.
For Nvidia Tegra platform, on some design, we are using only ID 
detection and hence this option get added.

I did not like to break the TI design/code and hence added the option 
such that if there is no initialisation of this member or dts entry then 
assume it as the cable detection is enabled. Hence it need explicitly 
entry for disable the cable type detction. This is what for platform 
data structure.

On other structure, I use as other way to use in rest of code to make 
logic as

if (palmas_usb->enable_id_detction)
    xxx.

rathar than

if (!palmas_usb->disable_id_detction)
    xxx.


On rest of code, do now wan to use the pdata.
