The PHYs hwtstamp callback are still getting the timestamp config from
ifreq and using copy_from/to_user.
Get rid of these functions by using timestamp configuration in parameter.
This also allow to move on to kernel_hwtstamp_config and be similar to
net devices using the new ndo_hwstamp_get/set.
This adds the possibility to manipulate the timestamp configuration
from the kernel which was not possible with the copy_from/to_user.

The driver can match only via the DT table so the table should be always
used and the of_match_ptr does not have any sense (this also allows ACPI
matching via PRP0001, even though it might not be relevant here). This
also fixes !CONFIG_OF error:
drivers/ptp/ptp_ines.c:783:34: error: ‘ines_ptp_ctrl_of_match’ defined but not used [-Werror=unused-const-variable=]

Since commit 94dd016ae538 ("bond: pass get_ts_info and SIOC[SG]HWTSTAMP
ioctl to active device") the user could get bond active interface's
PHC index directly. But when there is a failover, the bond active
interface will change, thus the PHC index is also changed. This may
break the user's program if they did not update the PHC timely.
This patch adds a new hwtstamp_config flag HWTSTAMP_FLAG_BONDED_PHC_INDEX.
When the user wants to get the bond active interface's PHC, they need to
add this flag and be aware the PHC index may be changed.
With the new flag. All flag checks in current drivers are removed. Only
the checking in net_hwtstamp_validate() is kept.

Remove driver internal defines for this. Masking msgtype with 0xf is
already done within ptp_get_msgtype().

Because kfree_skb already checked NULL skb parameter,
so the additional check is unnecessary, just remove it.

In order to reduce code duplication between ptp drivers, generic helper
functions were introduced. Use them.

Use the helper function that wraps the calls to platform_get_resource()

The '==' expression itself is bool, no need to convert it to bool again.
This fixes the following coccicheck warning:
drivers/ptp/ptp_ines.c:403:55-60: WARNING: conversion to bool not
needed here

The InES at the ZHAW offers a PTP time stamping IP core. The FPGA
logic recognizes and time stamps PTP frames on the MII bus. This
patch adds a driver for the core along with a device tree binding to
allow hooking the driver to MII buses.
