In dwxgmac_of_get_mac_mode there is a test for mac_mode which will
return if false. After this point mac_mode is guaranteed to be true so
there is no need to test for this. Remove that test.

This patch adds support for configuring the ethernet MAC mode independently
from the PHY mode on our SoC FPGA board. Specifically, this is necessary
for a scenario where the ethernet controller MAC is connected to the
FPGA HVIO with a different GMII interface, and the FPGA output is routed
to the PHY using a RGMII interface.
To support this configuration, a mechanism is introduced to handle
separate MAC mode settings, ensuring that the MAC controller and PHY
can operate correctly with their respective interface modes.
If mac-mode is not defined, the MAC mode will default to the PHY mode,
ensuring compatibility and proper operation between the MAC and PHY.

An issue was identified where selecting the phy-mode as
rgmii-id in the device tree source (DTS) would cause the
`dwc_eth_xgmac_socfpga` driver to raise an unsupported phy mode error.
From the MAC controller's perspective, the rgmii and rgmii-id
phy modes are effectively identical. To address this, both
modes will now be configured to rgmii in the MAC controller.
This change ensures that the rgmii-id phy mode is properly
supported without error.

As part of bringing the master branch back in to next, we need to allow
for all of these changes to exist here.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.
This reverts commit c8ffd1356d, reversing
changes made to 2ee6f3a5f7.

This driver support the Synopsys Designware Ethernet 10G
IP block refer from the driver dwc_eth_qos.
The driver MAC register mapping is different between
Synopsys QoS IP and Synopsys 10G IP, and thus new file
is created meant for Sysnopsys 10G IP.
The dwc_eth_xgmac_socfpga.c is specific to a device family,
the driver support the specific configuration used in
Intel SoC FPGA Agilex5.
This driver is extensible for other device family to use.
