code formatting

You can split field write chain on steps to make rustfmt happy.
For example instead of

        Self::register_block().int_clr().write(|w| {
            w.rxfifo_full_int_clr()
                .set_bit()
                .rxfifo_ovf_int_clr()
                .set_bit()
                .rxfifo_tout_int_clr()
                .set_bit()
                .at_cmd_char_det_int_clr()
                .set_bit()
        });

you can write:

        Self::register_block().int_clr().write(|w| {
            w.rxfifo_full_int_clr().set_bit();
            w.rxfifo_ovf_int_clr().set_bit();
            w.rxfifo_tout_int_clr().set_bit();
            w.at_cmd_char_det_int_clr().set_bit()
        });

This is due to the fact that w is &mut

Interesting, I find the latter much easier to parse, so maybe we should do this going forward 🤔
