fix(renesas): align incompatible function pointers

secure_boot_api_f is defined to take uint32_t, uint32_t, and void *
parameters. However rom_secure_boot_api_f is defined to take uint32_t *,
uint32_t *, void *. These are incompatible and cause a warning when
compiling with -Wextra. Align the rom definition to the more generic
definition from where it's called.
