Using 2500Base-T SFP modules e.g. on the BananaPi R3 requires manually
disabling auto-negotiation, e.g. using ethtool. While a proper fix
using SFP quirks is being discussed upstream, bring a work-around to
restore user experience to what it was before the switch to the
dedicated SGMII PCS driver.

It isn't feasible to literally backport all upstream phylink_pcs changes
down to Linux 5.15: It's just too many patches, and many downstream
drivers and hacks are likely to break. We are too close to branching off
to risk this, and it's also just too much work.
Instead just add helper functions used by modern PCS drivers while keeping
the original functions instact as well. While this may add a kilobyte or
two of extra kernel size, it has the advantage that we get the best of both
worlds: None of the existing codepaths are touched, but yet we have the
option to backport singular improvements to Ethernet drivers where needed.

Add a patch to allow modification of the PHY LED configuration. This is
required for boards, where the reset configuration of LED functions is
incompatibe with the usage of the device LEDs.
This is the case for the ASUS TUF-AX4200 Wireless router. It requires
modification of the LED configuration because as the WAN LED on the
front of the device is driven by the PHY. Without patching, it would
only illuminate in case the Link speed is 100 Mbit/s.

This can improve load balancing by pushing backlog (and RPS) processing
to separate threads, allowing the scheduler to distribute the load.
It can be enabled with: echo 1 > /proc/sys/net/core/backlog_threaded

1. Check for -EPROBE_DEFER
If it occurs we have to return immediately. Trying other properties
could result in another error and ignoring -EPROBE_DEFER which has a
special meaning.
2. Check for read result
Assuming property->read() success can result in NULL pointer
dereference. It happens e.g. for "mac-address" with NVMEM cell
containing invalid MAC.
3. Simplify code
Don't move cell reading & nvmem_cell_put() into a loop. Simplify loop
code.

As described in commit 97c77fff28
MV88E6xxx driver (NET_DSA_MV88E6XXX) cannot be built-in when PTP
(PTP_1588_CLOCK) is a module in Linux 5.15. But actually it should be
allowed to be built-in when its PTP support (NET_DSA_MV88E6XXX_PTP) is
disabled.
This adds a patch to fix that.

nvmem_cell_read return a pointer error when an error occurs. Currently
we convert the pointer error to an int while the rest of the function
return a void* and expcet an error pointer. Fix this PTR_ERR msuse

This DT property allows marking flash partition that Linux should use as
a root device. It's useful for devices that don't use U-Boot and cmdline
parser for partitioning. It may be used with "fixed-partitions" or some
dynamic partitioning based on flash content.
