When not using DM_ETH, these PHY settings are programmed with default
values hardcoded into the driver. When using DM_ETH, they should come
from the device tree. However, if the device tree does not have the
properties, the driver will silent use -1. Which is entirely out of
range, programs nonsense into the PHY's registers, and does not work.
Change this to use the same defaults as non-DM_ETH if the device tree is
lacking the properties.
As an alternative, the kernel driver for the phy will display an error
message and fail if the device tree is lacking.

Commit d397f7c45b ("net: phy: micrel: Separate KSZ9000 drivers from
KSZ8000 drivers") separated the KSZ8xxx and KSZ90x1 drivers and warns
that you shouldn't select both of them due to a device ID clash between
the KSZ9021 and the KS8721, asserting that "it is highly unlikely for a
system to contain both a KSZ8000 and a KSZ9000 PHY". Unfortunately
boards like the SAMA5D3xEK do contain both types of PHY, but fortunately
the Linux Micrel PHY driver provides a solution by using different PHY
ID and mask values to distinguish these chips.
This commit contains the following changes:
- The PHY ID and mask values for the KSZ9021 and the KS8721 now match
those used by the Linux driver.
- The warnings about not enabling both drivers have been removed.
- The description for PHY_MICREL_KSZ8XXX has been corrected (these are
10/100 PHYs, not GbE PHYs).
- PHY_MICREL_KSZ9021 and PHY_MICREL_KSZ9031 no longer select PHY_GIGE
since this is selected by PHY_MICREL_KSZ90X1.
- All of the relevant defconfig files have been updated now that
PHY_MICREL_KSZ8XXX does not default to 'Y'.

In some of the device trees that specify skew values for KSZ90x1 PHYs
the values are stored (incorrectly) in the MAC node, whereas in others
it is in an 'ethernet-phy' subnode. Previously the code would fail to
find and program these skew values, so this commit changes it to look
for an "ethernet-phy" subnode first, and revert to looking in the MAC
node if there isn't one.
The device trees affected (where the skew values are in a subnode) are
imx6qdl-icore-rqs.dtsi, r8a77970-eagle.dts, r8a77990-ebisu.dts,
r8a77995-draak.dts, salvator-common.dtsi, sama5d3xcm.dtsi,

socfpga_stratix10_socdk.dts and ulcb.dtsi. Before this change the skew
values in these device trees would be ignored.
The device trees where the skew values are in the MAC node are

socfpga_cyclone5_de0_nano_soc.dts, socfpga_cyclone5_de10_nano.dts,

Commit ff7bd212cb ("net: phy: micrel: fix divisor value for KSZ9031
phy skew") fixed the skew value divisor for the KSZ9031, but left the
code using the same divisor for the KSZ9021, which is incorrect.
The preceding commit c16e69f702 ("net: phy: micrel: add documentation
for Micrel KSZ90x1 binding") added the DTS documentation for the
KSZ90x1, changing it from the equivalent file in the Linux kernel to
correctly state that for this part the skew value is set in 120ps steps,
whereas the Linux documentation and driver continue to this day to use
the incorrect value of 200 that came from the original KSZ9021 datasheet
before it was corrected in revision 1.2 (Feb 2014).
This commit sorts out the resulting confusion in a consistent way by
making the following changes:
- Update the documentation to be clear about what the skew values mean,
in the same was as for the KSZ9031.
- Update the Micrel PHY driver to select the appropriate divisor for
both parts.
- Adjust all the device trees that state skew values for KSZ9021 PHYs to
use values based on 120ps steps instead of 200ps steps. This will result
in the same values being programmed into the skew registers as the
equivalent device trees in the Linux kernel do, where it incorrectly
uses 200ps steps (since that's where all these device trees were copied
from).
