herobrine_npcx9: Detect the Refresh key at row 3

Herobrine uses the Vivaldi keyboard. The Refresh key is at T2
(col:2, row:3), instead of T3 (col:2, row:2). The code filters out
the Refresh key and check any boot key remaining, like the Esc key.

Misconfiguring it fails the recovery boot, as EC detects a redundant
key pressed.

BRANCH=None
BUG=b:196885613
TEST=Pressed Refresh (T2) + Esc and booted EC. Checked the message:
  [0.005749 KB boot key mask 1]
which showed the Esc key was recognized.

Without this CL, the message won't show up, as a redundant key
(T2 not recognized as Refresh) is pressed.

Both EC-OS and Zephyr images behave the same.
