ARM: dts: stm32: add USB OTG wakeup management on stm32mp131

USB OTG can be used to wakeup from stop mode on stm32mp131. Add wakeup-source property, use EXTI torvalds#44 interrupt instead of GIC, and attach USB OTG to "pd_core" power domain. Change-Id: I2a1afd29c1b12aaf179eb44c3b333cb69f77bbac Signed-off-by: Amelie Delaunay <[email protected]>
