This patch adds r8a77990 xhci support. The driver will use
the fallback compatible string "renesas,rcar-gen3-xhci".

Signed-off-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com>

 After we applied the following patches, the driver will use
the fallback compatible string "renesas,rcar-gen3-xhci" on
r8a77990. (If we doesn't apply the patches, the driver cannot
get the firmware name, and then the probe on r8a77990 failed.)

Thanks.

FWIW I think we can still merge DTS patches to enable USB3 on E3 in
parallel with the above driver patches as enabling a device that was
previously not enabled won't cause a regression so long as the probe
failure doesn't cause other problems - f.e. kernel panic
