Can has generic implementation of ndo_eth_ioctl which implements only HW
timestamping commands. Implement generic ndo_hwtstamp callbacks and use
it in drivers instead of generic ioctl interface.

can_dropped_invalid_skb()
In addition to can_dropped_invalid_skb(), the helper function
can_dev_dropped_skb() checks whether the device is in listen-only mode and
discards the skb accordingly.
Replace can_dropped_invalid_skb() by can_dev_dropped_skb() to also drop
skbs in for listen-only mode.

can_change_mtu() became obsolete by commit 23049938605b ("can: populate the
minimum and maximum MTU values"). Now that net_device->min_mtu and
net_device->max_mtu are populated, all the checks are already done by
dev_validate_mtu() in net/core/dev.c.
Remove the net_device_ops->ndo_change_mtu() callback of all the physical
interfaces, then remove can_change_mtu(). Only keep the vcan_change_mtu()
and vxcan_change_mtu() because the virtual interfaces use their own
different MTU logic.
The only functional change this patch introduces is that now the user will
be able to change the MTU even if the interface is up. This does not matter
for Classical CAN and CAN FD because their MTU range is composed of only
one value, respectively CAN_MTU and CANFD_MTU. For the upcoming CAN XL, the
MTU will be configurable within the CANXL_MIN_MTU to CANXL_MAX_MTU range at
any time, even if the interface is up. This is consistent with the other
net protocols and does not contradict ISO 11898-1:2024 as having a
modifiable MTU is a kernel extension.

This patch adds support for one-shot mode. In this mode there happens no
automatic retransmission in the case of an arbitration lost error or on
any bus error.

Rename macros to use for esdACC CTRL register access to match the
internal documentation and to make the macro prefix consistent.
- ACC_CORE_OF_CTRL_MODE -> ACC_CORE_OF_CTRL
Makes the name match the documentation.
- ACC_REG_CONTROL_MASK_MODE_ -> ACC_REG_CTRL_MASK_
ACC_REG_CONTROL_MASK_ -> ACC_REG_CTRL_MASK_
Makes the prefix consistent for macros describing masks in the same
register (CTRL).

This patch adds support for the PCI based PCIe/402 CAN interface family
from esd GmbH that is available with various form factors
(https://esd.eu/en/products/402-series-can-interfaces).
All boards utilize a FPGA based CAN controller solution developed
by esd (esdACC). For more information on the esdACC see
https://esd.eu/en/products/esdacc.
This driver detects all available CAN interface board variants of
the family but atm. operates the CAN-FD capable devices in
Classic-CAN mode only! A later patch will introduce the CAN-FD
functionality in this driver.
