rp/pio: don't call dma::init so much
this is already done during platform init. it wasn't even sound in the
original implementation because futures would meddle with the nvic in
critical sections, while another (interrupt) executor could meddle with
the nvic without critical sections here. it is only accidentally sound
now and only if irq1 of both pios isn't used by user code. luckily the
worst we can expect to happen is interrupt priorities being set wrong,
but wrong is wrong is wrong.
