sun8i_emac: add support for setting EMAC TX/RX delay

Some boards have the EMAC TX/RX lanes wired with a different length with
the clock lane, which can be workarounded by setting a TX/RX delay in
the EMAC.

This kind of delays are already defined in the newest device tree
binding of dwmac-sun8i, which has already entered linux-next.

Add support for setting these delays.

net: sun8i-emac: support R40 GMAC

Add support for the GMAC found in the Allwinner R40/V40 SoC.

The R40 GMAC interface is not controlled by the syscon register but
has a separate configuration register in the CCU.
The clock gate and reset bits are in a different register compared
to the other SoCs supported by this driver.
The driver uses the -gmac suffix for the R40 because the R40 also
has a different 100 MBit MAC (EMAC).

SPDX: Convert all of our single license tags to Linux Kernel style

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

The original DT binding used by U-Boot's sun8i-emac driver was not really

net: sun8i-emac: add support for new EMAC DT binding

The Ethernet MAC used in newer Allwinner SoCs (H3, A64, H5) got an
upstream Linux driver in v4.15.
This one uses a slightly different binding from the original one used
by the U-Boot driver.
The differences to the old binding are:
- The "syscon" address is held in a separate node, referenced via a
phandle in the "syscon" property.
- The reference to the PHY is held in a property called "phy-handle",
not "phy".
- The PHY register is at offset 0x30 in the syscon device, not at 0.
- The internal PHY is activated when the node, which phy-handle points
to, is a child node of an "allwinner,sun8i-h3-mdio-internal" node.

Teach the U-Boot driver how to find its resources in a "new-style" DT,
so that we can use a Linux kernel compatible DT for U-Boot as well.
This keeps support for the old binding for now, to allow a smooth
transition.

The Linux kernel driver for the Allwinner pin controller gained support

The sun8i-emac Ethernet driver for new Allwinner MACs reads the pins from
the DT, but so far only supported the old binding.
Update the parsing routine to cope with both the old and new bindings,
so that the newer DTs can be used with U-Boot and its Ethernet driver.

dm: Rename dev_addr..() functions

These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.

In the end we will have:

1. dev_read_addr...() - works on devices, supports flat/live tree
2. devfdt_get_addr...() - current functions, flat tree only
3. of_get_address() etc. - new functions, live tree only

All drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.

Note this involves changing some dead code - the imx_lpi2c.c file.
