[PATCH] xhci: host: renesas: drop excessive Kconfig selects

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

The USB_XHCI_RZV2M and USB_RENESAS_USB3 select other drivers
based on the enabled SoC types, which leads to build failures
when the dependencies are not met:

WARNING: unmet direct dependencies detected for USB_RZV2M_USB3DRD
  Depends on [n]: USB_SUPPORT [=y] && USB_GADGET [=n] && (ARCH_R9A09G011 [=n] || COMPILE_TEST [=y])
  Selected by [m]:
  - USB_XHCI_RZV2M [=m] && USB_SUPPORT [=y] && USB [=y] && USB_XHCI_HCD [=m] && USB_XHCI_PLATFORM [=m] && (ARCH_R9A09G011 [=n] || COMPILE_TEST [=y])
ERROR: modpost: "rzv2m_usb3drd_reset" [drivers/usb/host/xhci-plat-hcd.ko] undefined!

All the selected symbols are actually user visible, so the correct
approach here is to drop the incorrect 'select' statements and
have users turn on those drivers during kernel configuration as
they would for any other driver.
