rp2/rp2_pio: Allow more than 8 consecutive pins for PIO out/set/sideset.
rp2/rp2_pio: Allow more than 8 consecutive pins for PIO out/set/sideset.

The bitmasks supplied for initialization of out/set/sideset were only 8 bit
instead of 32.  This resulted in an error, that not more than 8 consecutive
pins would get initialized.

Fixes issue #6933.
