Add support for WIZ module present in TI's J721E SoC. WIZ is a SERDES
wrapper used to configure some of the input signals to the SERDES. It is
used with both Sierra(16G) and Torrent(10G) SERDES. This driver configures
three clock selects (pll0, pll1, dig) and supports resets for each of the
lanes.
This is an adaptation of the linux driver.

Add a Sierra PHY driver with PCIe and USB support.
This driver is a port from the mainline linux driver.
The PHY has multiple lanes, which can be configured into
groups, and a generic PHY device is created for each group.
There are two resets controlling the overall PHY block, one
to enable the APB interface for programming registers, and
another to enable the PHY itself. Additionally there are
resets for each PHY lane.
The PHY can be configured in hardware to read register
settings from ROM, or they can be written by the driver.
The sequence of operation on startup is to enable the APB
bus, write the PHY registers (if required) for each lane
group, and then enable the PHY. Each group of lanes
can then be individually controlled using the power_on()/
power_off() function for that generic PHY
One difference with the linux driver is that the PHY is
always reset after it is powered-on. This is because role
switching is not supported in u-boot and the cable
orientation is handled by the PHY reset.

The AB8500 PMIC contains an USB PHY that needs to be set up in
device or host mode to make USB work properly. Add a simple driver
for the generic PHY uclass that allows enabling it.
The if (CONFIG_IS_ENABLED(USB_MUSB_HOST)) might be a bit strange.
The USB PHY must be configured in either host or device mode and
somehow the USB PHY driver must be made aware of the mode.
Actually, the MUSB driver used together with this PHY does not
support dynamic selection of host/device mode in U-Boot at the moment.
Therefore, one very simple approach that works fine is to select
the mode to configure at compile time. When the MUSB driver is
configured in host mode the PHY is configured in host mode, and
similarly when the MUSB driver is configured in device/gadget mode.

the SERDES uses for Clock Multiplier Unit (CMU refclock).
The PLL mux clock can select from one of the three input
clocks. The right output can select between left input and
external reference clock while the left output can select
between the right input and external reference clock.
The driver has support to select PLL mux and left/right output

This driver is derived from this Linux driver:
linux/drivers/phy/ralink/phy-ralink-usb.c
The driver sets up power and host mode, but also needs to configure PHY
registers for the MT7628 and MT7688.
I removed the reset controller handling for the USB host and device, as
it does not seem to be necessary right now. The soft reset bits for both
devices are enabled by default and testing has shown (with hackish
reset handling added), that USB related commands work identical with
or without the reset handling.
Please note that the resulting USB support is tested only very minimal.
I was able to detect one of my 3 currently available USB sticks.
Perhaps some further work is needed to fully support the EHCI controller
integrated in the MT76x8 SoC.
