This binding only describes the USB phy inside the USB3 + DP "combo"
phy. Add information for the DP phy and describe the sub-nodes that
represent the DP and USB3 phys that exist inside the combo wrapper.
Remove reg-names from required properties because it isn't required nor
used by the kernel driver.

When WIZ wraps a Cadence Torrent PHY (instead of Cadence Sierra PHY)
there is a difference in the refclk-dig node: Torrent only has two
clocks instead of Sierra's four clocks. Add minItems: 2 to solve this.
Additionally, in our use case we only need to use assigned-clock for a
single clock, but the current binding requires either no assigned-clocks
or two. Fix this by adding minItems: 1 to all the assigned-clock
properties.
There was also an extra trailing whitespace, which this patch removes.

There are no dts files using torrent phy yet, so it is safe to add a new
required property.

Fix a Kconfig warning that is causing lots of build errors
when USB_SUPPORT is not set.
USB_PHY depends on USB_SUPPORT but "select" doesn't care about
dependencies, so this driver should also depend on USB_SUPPORT.
It should not select USB_SUPPORT.
WARNING: unmet direct dependencies detected for USB_PHY
Depends on [n]: USB_SUPPORT [=n]
Selected by [m]:
- USB_LGM_PHY [=m]

Added support for multilink configuration of Torrent PHY. Currently,
maximum two links are supported. In case of multilink configuration,
PHY needs to be configured for both the protocols simultaneously at
the beginning as per the requirement of Torrent PHY.
Also, register sequences for PCIe + SGMII/QSGMII Unique SSC PHY multilink
configurations are added.

Torrent PHY can be used in different multi-link multi-protocol
configurations including protocols other than DisplayPort also,
such as PCIe, USB, SGMII, QSGMII etc. Update the bindings to have
support for these configurations.

On K3 AM654x/J721E platforms the Port MII mode selection register(s) have
similar format and placed in the System Control Module (SCM) module
sequentially as one register per port, but, depending SOC and CPSW
instance, the base offset and number of ports can be different.
Hence, add possibility to retrieve number of ports and base registers
offset from DT and support for max possible number of ports supported by K3
SoCs like J721E.
