Subject: [PATCH] embassy-rp: fix set_input_sync_bypass pin offset

currently this function causes a crash in debug mode when used with pins greater than
32 (available on the rp235xb variant) because it overflows when doing
the shift. this commit applies the GPIOBASE offset to pin value before doing the
shift.
