IIRC not all the pads over here have any IO control. Some are analog pins
and some like JTAG, PORz really shouldn't be meddled with if the h/w does
expose some configuration. Please revisit this change.

SLEWCTRL is typically not changed. You might want to double check this portion
with the h/w folks.
