staging: unisys: refactor ULTRA_CONTROLVM_PARAMETERS_HEADER

Browse Source 
Remove the typedef from ULTRA_CONTROLVM_PARAMETERS_HEADER, and use struct
spar_controlvm_parameters_header instead. Fix CamelCase names in the structure,
and update references to fixed names in other files and the comments.
