nyan*: pinmux: fix PWM1/2 conflicts
GPIO_PU4/PH1 and _PU5/PH2 were set to use the same PWM1/2 SFIO.
Even though no problems were caused by this, correct it here
so we get a conflict-free pinmux map.
BUG=chrome-os-partner:27091
BRANCH=none
TEST=Built and booted on Nyan, ran TegraShell "pinmux check"
and saw no conflicts.
