[PATCH v3 2/2] usb: musb: da8xx: depopulate OF children on remove

da8xx_probe() creates CPPI platform devices with of_platform_populate(),
but da8xx_remove() unregisters only the separately created MUSB device and
the generic PHY. The OF children therefore remain registered after the
glue driver is unbound.
Pair the successful population with of_platform_depopulate() during remove.
Unregister the MUSB device first because it reuses the parent DT node but
was not created by of_platform_populate().
Fixes: d6299b6efbf6 ("usb: musb: Add support of CPPI 4.1 DMA controller to DA8xx")
