Matched some controller files (#178)

* osPfsIsPlug.c and osContSetCh.c OK

* update

* __osPfsGetStatus.c OK

* removed unused asm

* Updated all libultra controller files to use new structs instead of the temporary structs. Added os_pfs.h

* controller updates

* fixed header guard

* Made suggested changes
