phy: renesas: Add Renesas Ethernet SERDES driver for R-Car S4-8

Add Renesas Ethernet SERDES driver for R-Car S4-8 (r8a779f0).
The datasheet describes initialization procedure without any information
about registers' name/bits. So, this is all black magic to initialize
the hardware. Especially, all channels should be initialized at once.

phy: Renesas R-Car gen3 PCIe PHY driver

This PHY is still mostly undocumented -- the only documented registers
exist on R-Car V3H (R8A77980) SoC where this PHY stays in a powered-down
state after a reset and thus we must power it up for PCIe to work...

The USB 3.0 PHY modules of R-Car Gen3 SoCs have:
- Spread spectrum clock (ssc).
- Using USB 2.0 EXTAL clock instead of USB 3.0 clock.
- Enabling VBUS detection for usb3.0 peripheral.

So, this driver supports these features.
