In some cases the link on the system interface of the aquantia PHY comes up
after the link on line interface. The link state loop only checks the line
side, which may result in first packet sent being lost.
Use aquantia_link_is_up instead, which checks both system and line side on
gen 2/3 PHYs to avoid losing the 1st packet.

Aquantia PHYs have a SMBus interface mostly used for debug. The addresses
on this interface are normally set up by PHY firmware, but depending on the
board they may end up not being unique. Add an optional DT property used
to change SMBus address if needed.

MDI pins up to the RJ45 connector may be reversed on the board and the
default PHY configuration applied by firmware may or may not match that.
Add an optional DT property to configure MDI reversal for this case.

If PHY is not ready for data by the time _config is called, reconfigure the
PHY system interface to use the proper protocol based on phydev->interface,
just in case the defaults set by PHY firmware don't match current
configuration.

Uses the data field in phy_driver structure to identify the PHY generation.
This is useful for custom configuration as non-generic PHY registers are
not 100% compatible between generations.

The PHY supports XFI and USXGMII, the notable difference being that USX AN
is enabled for USXGMII. Legacy code uses XGMII for any 10G proto and
detects whether USX AN should be enabled or not using a PHY status
register. Keep that functionality too, so we don't break existing drivers.

For AQR405 in register 4.c441 bit 15 was override with 0. This caused the
phy to not negotiate at 2.5GB rate with mac. To avoid
this override it needed first to know the previous value of reg 4.c441
and set only bit 3.

This merges the CRC16-CCITT headers into u-boot/crc.h to prepare for
rolling CRC16 into the hash infrastructure. Given that CRC8, CRC32
and CRC32-C already have their prototypes in a single header file, it
seems a good idea to also include CRC16-CCITT in the same.

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.
