Local function `set_transforms` has a parameter of type `struct
jr3_pci_transform`. This has a size 32 bytes, which is quite large for
passing around in a function call. Change it to use type `const struct
jr3_pci_transform *`. (In practice, it is probably inlined by the
compiler anyway, but doing this seems to save a few bytes.)
