The phydev structure is present in both ldpaa_eth_priv and
wriop_dpmac_info. the phydev in wriop_dpmac_info is not being used
As the phydev is created based on phy_addr and bus members of
wriop_dpmac_info, it is appropriate to keep phydev in wriop_dpmac_info.
Also phy_regs is not being used, therefore remove it

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

Existing MC driver framework is based on MC-9.x.x flib. This patch
migrates MC obj (DPBP, DPNI, DPRC, DPMAC etc) to use latest MC flib
which is MC-10.3.0.
Changes introduced due to migration:
1. To get OBJ token, pair of create and open API replaces create APIs
2. Pair of close and destroy APIs replaces destroy APIs
3. For version read, get_version APIs replaces get_attributes APIs
4. dpni_get/reset_statistics APIs replaces dpni_get/set_counter APIs
5. Simplifies struct dpni_cfg and removes dpni_extended_cfg struct
6. Single API dpni_get_buffer_layout/set_buffer_layout replaces
dpni_get_rx/set_rx, tx related, tx_conf_buffer_layout related APIs.
New API takes a queue type as an argument.
7. Similarly dpni_get_queue/set_queue replaces
dpni_get_rx_flow/set_rx_flow , tx_flow related, tx_conf related
APIs

Management Complex FW 9.0 set the hardware depletion to be 20
buffers in order to support multiple pools in DPNI. This requires
driver to fill the pool with at least 21 to be able to receive
frames. So, Increase number of buffers for a pool.

MC 0.7.1.2 enforces limitation i.e.: "Packets may be corrupted
in several combinations of buffer size and frame offsets.
Workaround: Use buffers that are of size that is a multiple of 256, and
frame offset that is a multiple of 256"
Updating the DPNI Eth driver to comply with the restriction.

As per current implementation of DPAA2 ethernet driver DPNI is used as
net device. DPNI is tangible objects can be multiple connected to same physical lane.
Use DPMAC as net device where it represents physical lane.
Below modification done in driver
- Use global DPNI object
- Connect DPMAC to DPNI
- Create and destroy DPMAC

Wire rate IO Processor (WRIOP) provide support of receive and transmit
ethernet frames from the ethernet MAC. Here Each WRIOP block supports
upto 64 DPMACs.
Create a house keeping data structure to support upto 16 DPMACs and
store external phy related information.

LDPAA Ethernet driver is a freescale's new ethernet driver based on
Layerscape architecture.
Every ethernet driver controls on DPNI object. Where all DPNIs share
one common DPBP and DPIO object to support Rx and Tx flows.
