It is possible that users of generic_phy_*() APIs may pass a valid
struct phy pointer but phy->dev can be NULL, leading to NULL pointer
deference in phy_dev_ops().
So call generic_phy_valid() to verify that phy and phy->dev are both
valid.

Clients that are requesting some of uclass API's
without a device (with ofnode) usually have _nodev
naming convention.
- clk_get_by_index_nodev
- clk_get_by_name_nodev
- reset_get_by_index_nodev
- gpio_request_by_name_nodev
So, update the same naming convention PHY framework.
This doesn't change the existing functionality.

Usually the digital and analog phys use the same reference clock,
but some platforms have two separate reference clocks for each of
them, so add another optional clock to support them.
In order to keep the clock names consistent with PHY IP's, change
the da_ref for analog phy and ref clock for digital phy.

[narmstrong: fixed by including ofnode.h in generic-phy.h]
At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.
Move the compatibility features into a separate header file.

At present devres.h is included in all files that include dm.h but few

Add a new SERDES driver for TI's AM654x SoC which configures
the SERDES only for PCIe. Support fo USB3 can be added later.
SERDES in am654x has three input clocks (left input, external
reference clock and right input) and two output clocks (left
output and right output) in addition to a PLL mux clock which
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
mux as specified in device tree.

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.
