trace-debug[stm]: Fix for BT/WLAN instability
Pins under mop500_ske_pins array are used for different
functionalities in snowball. Ex: GPIO161 pin configured
for keypad here must stay configured as GPIO alternate
function for operating PMU_EN pin of BT/WLAN chip
in snowball. So forbid configuring these pins, for snowball
