AFAIK they really do have identical pinmux, I'll double check the
pinmux spreadsheet to make sure.

There's another unintended side effect of reusing the venice2 board
this way that I discovered after posting this.  It causes
CONFIG_SYS_BOARD to be set to venice2 still, which causes the
"board_name" environment variable to be set to venice2, which causes
boot.scr to look for a venice2 dtb.

It may be cleaner to make norrin a proper board, and just have it
#include the vencie2 pinmux.
