Revert "phy: realtek: usb: Add driver for the Realtek SoC USB 2.0 PHY"

commit 7a784bcdd7e54f0599da3b2360e472238412623e upstream.

This reverts commit 134e6d25f6bd06071e5aac0a7eefcea6f7713955.

The recently added Realtek PHY drivers depend on the new port status
notification mechanism which was built on the deprecated USB PHY
implementation and devicetree binding.

Specifically, using these PHYs would require describing the very same
PHY using both the generic "phy" property and the deprecated "usb-phy"
property which is clearly wrong.

We should not be building new functionality on top of the legacy USB PHY
implementation even if it is currently stuck in some kind of
transitional limbo.

Revert the new Realtek PHY drivers for now so that the port status
notification interface can be reverted and replaced.

media: tc358746: select CONFIG_GENERIC_PHY

The tc358746 driver selects CONFIG_GENERIC_PHY_MIPI_DPHY and links to
that, but this fails when CONFIG_GENERIC_PHY is disabled, because Kbuild
then never enters the drivers/phy directory for building object files:

ERROR: modpost: "phy_mipi_dphy_get_default_config_for_hsclk" [drivers/media/i2c/tc358746.ko] undefined!

Add an explicit 'select GENERIC_PHY' here to ensure that the directory
is entered, and add another dependency on that symbol so make it
more obvious what is going on if another driver has the same problem,
as this will produce a Kconfig warning.

The X-Gene PHY driver is unlikely to be useful on a kernel without general

specific platform support. Narrow the dependency to ARCH_XGENE like we do
for other X-Gene specific drivers to ensure that users who have configured
down the set of platforms enabled don't see the option.
