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).

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

Getting a RESET by index with device is not straight forward
for some use-cases like handling clock operations for child
node in parent driver. So we need to process the child node
in parent probe via ofnode and process RESET operation for child
without udevice but with ofnode.
So add reset_get_by_index_nodev() and move the common code

The EFI implementation of reset sits inside the driver and is called
directly from outside the driver, breaking the normal driver-model
conventions. Worse, it passed NULL as the device pointer, hoping that
the called function won't use it, which breaks as soon as code is added
to use it.
Separate out the implementation to improve the situation enough to allow
a future patch to add new sysreset features.

When EEE is supported by the PHY and the driver allows it, libphy in the
kernel is configuring the PHY to stop receiving the xMII clock while it
is signaling LPI. While this (usually) works fine in the kernel this is
causing issues in U-Boot when rebooting from the linux kernel with this
bit set (without having the possibility to reset the PHY) where the PHY
suddenly stops working.
A new quirk is introduced to unconditionally reset this bit. If the
quirk is not enabled using the proper configuration symbol, the PHY state
is not changed.

Two new helper functions (phy_read_mmd() and phy_write_mmd()) are added
to allow access to the MMD PHY registers.
The MMD PHY registers can be accessed by several means:
1. Using two new MMD access function hooks in the PHY driver. These
functions can be implemented when the PHY driver does not support the
standard IEEE Compatible clause 45 access mechanism described in clause
22 or if the PHY uses its own non-standard access mechanism.
2. Direct access for C45 PHYs and C22 PHYs when accessing the reachable
DEVADs.
3. The standard clause 45 access extensions to the MMD registers through
the indirection registers (clause 22) in all the other cases.
