The U_BOOT_DRIVER macro creates a list of drivers used at link time, and
all entries here must be unique. This in turn means that all entries in
the code should also be unique in order to not lead to build failures
later with unexpected build combinations. Typically, the problem we have
here is when a driver is obviously based on another driver and didn't
update this particular field and so while the name field reflects
something unique the linker entry itself is not. In a few places this
provides a more suitable string name as well, however.

- Move DMA software reset and pad calibration in xgmac_start() to occur
  after the PHY is initialized and connected.
- This ensures the PHY is ready before performing these operations,
  which is necessary for proper recovery after reboot.

This change fixes issues where the PHY did not recover from power-down
state after a Linux reboot, for the board using Micrel KSZ90x1 PHY.

In xgmac_probe there is a direct return after the point where unwind
gotos start to be used to undo actions performed by earlier code. Use
the appropriate unwind goto instead.

This issue was found by Smatch.

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 c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

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.
