HID: core: Change hid_driver to use a const char* for name

name is never mutated by the core HID stack. Making name a const char*
simplifies passing the string from Rust to C. Otherwise, it becomes
difficult to pass a 'static lifetime CStr from Rust to a char*, rather than
a const char*, due to lack of guarantee that the underlying data of the
CStr will not be mutated by the C code.
