Change the last "depends on GENERIC_PHY" to use select, like the
other 170+ Kconfig users do. This can help prevent circular
dependency issues.

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.

This patch adds support for r8a77470 (RZ/G1C). We can reuse this driver for
initializing timing/interrupt generation registers.

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...

When USB is disabled, we get a link error for this driver
because of the added OTG support
drivers/phy/renesas/phy-rcar-gen3-usb2.o: In function `rcar_gen3_phy_usb2_probe':
phy-rcar-gen3-usb2.c:(.text+0x250): undefined reference to `of_usb_get_dr_mode_by_phy'
Other phy drivers select USB_COMMON for this, so let's do the same
here.
Fixes: 7e0540f41332 ("phy: rcar-gen3-usb2: check dr_mode for otg mode")

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.

Adding vendor specific directories in phy to group
phy drivers under their respective vendor umbrella.
Also updated the MAINTAINERS file to reflect the correct
directory structure for phy drivers.
