[PATCH v2 3/3] ARM: dts: stm32: Use STM32MP15xx compatible string for EHCI USB controller

[Marek Vasut <marex@nabladev.com>]

Use accurate STM32MP15xx compatible string for EHCI USB controller in
addition to "generic-ehci" fallback compatible string. This is future
proof, and drivers can match on the accurate compatible string in case
they need to discern this controller from the generic-ehci one.
