[PATCH] arm64: dts: renesas: salvator-common: add pfc node for USB3.0 channel 0

[Yoshihiro Shimoda]

Since a R-Car Gen3 bootloader enables the PFC of USB3.0 channel 0,
the USB3.0 host controller works without this setting on the kernel.
But, this setting should have salvator-common.dtsi. So, this patch
adds the pfc node for USB3.0 channel 0.

 This patch is based on the renesas.git / renesas-devel-20171002-v4.14-rc3 tag.

 Since related patches are already merged into renesas-drivers.git / 
 sh-pfc-for-v4.15, this patch is possible to apply for v4.15, I think.
