boards/risc-v/eic7700x: Report the pads at startup.

Browse source 
Log one line from board start up with the pad count and how many differ
from their reset defaults, through eic7700x_pinctrl_count().  A helper
holds its locals so nothing stays on the stack for the bring up that
follows.

Turn the pinctrl driver's error output on for both boards, so a refused
pad write says why rather than merely failing.
