Convert the mach info, and store the udc_command in the pxa_udc control
structure.

It is to be noticed that the udc_is_connected() in mach info is not
transfered. This was not used, as mioa701 machine doesn't need it,
balloon3 doesn't really use it, and most importantly the current driver
never uses it.
