Device bus address might not be valid for direct access when the bus
address and CPU address are not the same. Use dev_bus_to_phys() to
translate bus address back to CPU address.

If the MII interface is used, the PHY is the clock master, thus don't
set the clock rate. On Zynq-7000, this will prevent the following
error:
  zynq_gem ethernet@e000b000: failed to set tx clock rate 25000000

With commit cc4e8af2c552, fsl_enetc register accessors have been split to
handle different register offsets on different SoCs. However, for
internal MDIO register calculation, only ENETC_PM_IMDIO_BASE was fixed
without adding the SoC specific MAC register offset.

As a result, the network support for the Kontron SMARC-sAL28 and
probably other boards based on the LS1028A CPU is broken.

Add the SoC specific MAC register offset to calculation of imdio.priv to
fix this.

Currently, Synopsis xgmac driver only works if DMA region is under 4GB.
This change enables the DMA buffers allocations above 4GB memory

Add RMII-specific handling to rk3288_gmac_fix_mac_speed() so that it
properly sets the RMII clock (2.5 MHz vs. 25 MHz) and speed bits
(10 Mbps vs. 100 Mbps). Also define a new rk3288_gmac_set_to_rmii()
function to set the PHY interface field and RMII_MODE bit.

The Renesas R9A07G044L (RZ/G2L) SoC includes two Gigabit Ethernet
interfaces which can be supported using the ravb driver. Some RZ/G2L
specific steps need to be taken during initialization due to differences
between this SoC and previously supported SoCs. We also need to ensure
that the module reset is de-asserted after the module clock is enabled
but before any Ethernet register reads/writes take place.
