dwmac510_tc_ops and dwxgmac_tc_ops are completely identical,
keep dwmac510_tc_ops to provide better backward compatibility.

The extern declarations should be in a header file that corresponds to
their definition, move these extern declarations to its header file.
Some of them have nowhere to go, so move them to hwif.h since they are
referenced in hwif.c only.
dwmac100_* dwmac1000_* dwmac4_* dwmac410_* dwmac510_* stay in hwif.h,
otherwise you will be flooded with name conflicts from dwmac100.h,
dwmac1000.h and dwmac4.h if hwif.c try to #include these .h files.
Compile tested only.
No functional change intended.

In GMAC3_X, the timestamping configuration differs from GMAC4 in the
layout of the registers accessed to grab the number of snapshots in FIFO
as well as the register offset to grab the aux snapshot timestamp.
Introduce dedicated ops to configure timestamping on dwmac100 and
dwmac1000. The latency correction doesn't seem to exist on GMAC3, so its
corresponding operation isn't populated.

The PTP configuration for GMAC3_X differs from the other implementations
in several ways :
- There's only one external snapshot trigger
- The snapshot configuration is done through the PTP_TCR register,
whereas the other dwmac variants have a dedicated ACR (auxiliary
control reg) for that purpose
- The layout for the PTP_TCR register also differs, as bits 24/25 are
used for the snapshot configuration. These bits are reserved on other
variants.
On GMAC3_X, we also can't discover the number of snapshot triggers
automatically.
The GMAC3_X has one PPS output, however it's configuration isn't
supported yet so report 0 n_per_out for now.
Introduce a dedicated set of ptp_clock_info ops and configuration
parameters to reflect these differences specific to GMAC3_X.
This was tested on dwmac_socfpga.

FPE implementation for DWMAC4 and DWXGMAC differs only for:
1) Offset address of MAC_FPE_CTRL_STS and MTL_FPE_CTRL_STS
2) FPRQ(Frame Preemption Residue Queue) field in MAC_RxQ_Ctrl1
3) Bit offset of Frame Preemption Interrupt Enable
Refactor FPE functions to avoid code duplication and
to simplify the code flow by avoiding the use of
function pointers.

Fix EST offset for dwmac 5.10.
Currently configuring Qbv doesn't work as expected. The schedule is
configured, but never confirmed:
|[ 128.250219] imx-dwmac 428a0000.ethernet eth1: configured EST
The reason seems to be the refactoring of the EST code which set the wrong
EST offset for the dwmac 5.10. After fixing this it works as before:
|[ 106.359577] imx-dwmac 428a0000.ethernet eth1: configured EST
|[ 128.430715] imx-dwmac 428a0000.ethernet eth1: EST: SWOL has been switched
Tested on imx93.

Refactor EST implementation by moving common code for DWMAC4 and
DWXGMAC IPs into a separate EST module. EST implementation for DWMAC4
and DWXGMAC differs only for CSR base address, PTOV field offset
width, and PTOV clock multiplier value.
Thanks, Serge Semin and Jakub Kicinski for the suggestions on

This patch adds support for platform-specific reset logic in the
stmmac driver. Some SoCs require a different reset mechanism than
the standard dwmac IP reset. To support these platforms, a new function
pointer 'fix_soc_reset' is added to the plat_stmmacenet_data structure.
The stmmac_reset in hwif.h is modified to call the 'fix_soc_reset'
function if it exists. This enables the driver to use the platform-specific
reset logic when necessary.

PTP and MMC modules base address can depend on the GMAC version. As this
is HW specific lets move this base address calculation to hwif.c. Also,
add an entry in the HW table so that we can specify the module offset.
This can later be extended to more modules, if deemed necessary.

This adds support for U32 filter by using an HW only feature called
Flexible RX Parser. This allow us to match any given packet field with a
pattern and accept/reject or even route the packet to a specific DMA
channel.
Right now we only support acception or rejection of frame and we only
support simple rules. Though, the Parser has the flexibility of jumping to
specific rules as an if condition so complex rules can be established.
This is only supported in GMAC5.10+.
The following commands can be used to test this code:
1) Setup an ingress qdisk:
# tc qdisc add dev eth0 handle ffff: ingress
2) Setup a filter (e.g. filter by IP):
# tc filter add dev eth0 parent ffff: protocol ip u32 match ip \
src 192.168.0.3 skip_sw action drop
In every tests performed we always used the "skip_sw" flag to make sure
only the RX Parser was involved.

Move all the core version detection to a common place ("hwif.c") and
implement a table which can be used to lookup the correct callbacks for
each IP version.
This simplifies the initialization flow of each IP version and eases
future implementation of new IP versions.
