Its been decided that all NXP BT/ WiFi FW names won't support _v0 suffix.
The suffix would be kept for next HW versions such as v1, v2 and so on,
which do not have backward compatible FW.
This change affects W8987, IW416 and IW615 chipsets, out of which new FW

The PTP_TCR (Timestamp Control Register) is used to configure several
features related to packet timestamping.
On one hand, it configures the 1588 packet processing, to indicate what
types of frames should be timestamped (all, only 1588v1 or 1588v2, using
L2 or L4 timestamping, on IPv4 or IPv6, etc.). This is congfigured
usually through the ioctl / ndo dedicated for such setup. This
configuration is done by setting some fields in that register, that seem
to behave the same way on all dwmac variants, including DWMAC1000.
On the other hand, and only on DWMAC1000 apparently, some fields in that
register are used to configure external snapshots (bits 24/25).
On DWMAC4 and others, these fields are reserved and external
snapshots are configured through a dedicated register that simply
doesn't seem to exist on DWMAC1000.
This configuration is done in the dwmac1000-specific ptp_clock_info ops
(cf dwmac1000_ptp_enable()).
So to avoid the timestamping configuration interfering with the external
snapshots, this commit makes sure that the config_hw_tstamping only
configures the relevant bits in PTP_TCR, so that the DWMAC1000
timestamping can correctly rely on these otherwise reserved fields.

The default configuration for the interrupts on dwmac1000 have the
timestamping interrupt masked. Now that the timestamping has been
adapted to dwmac1000, enable the timestamping interrupt on these
platforms.
On dwmac1000, the external snapshot interrupt is configured through a
dedicated bit, that is set as reserved on other dwmac variants. The
timestaming interrupt is acknowledged by reading the
GMAC3_X_TIMESTAMP_STATUS register.
Make sure that this interrupt is enabled when snapshot is enabled, and
masked when disabled.

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.

Instead of modifying the global definition, then copying into the local
private data, let's first copy then modify the local parameters.
