Some USB controller drivers that depend on the xhci-plat driver
specify this dependency using 'select' in Kconfig. This is not
recommended for symbols that have other dependencies as it may
lead to invalid configurations. Use 'depends on' to specify the
dependency instead of 'select'.

For dwc3 specify the dependency on USB_XHCI_PLATFORM in
USB_DWC3_HOST and USB_DWC3_DUAL_ROLE. Also adjust the
dependencies of USB_DWC3_CORE to make sure that at least one
of USB_DWC3_HOST, USB_DWC3_GADGET or USB_DWC3_DUAL_ROLE can be
selected.

Hi,

I don't know what this all is about, perhaps I'm CC'ed semi-randomly
because touched that Kconfig once.

All I can say here is that the commit message tells us "This is not
recommended" and doesn't explain what's the actual problem is being
solved. If there is no real problem, why bother?
