staging: vc04_services: Replace typedef with struct

Using typedef for a structure type and upper case struct names is not
suggested in Linux kernel coding style guidelines. Hence, occurences
of typedefs have been removed and struct names converted to lowercase
in the file. Grep was also used to ensure that all occurence of the
typedefs have been removed. The module compiles without any warnings
or errors.
