Older DesignWare Ethernet MAC versions that this driver supports can
only work with 32-bit DMA source/destination addresses. Some platforms
have no physical RAM at the lowest 4GB address space. For these
platforms the driver must translate DMA addresses to/from physical
memory addresses.
Call translation routines so that properly configured platforms can use
the DesignWare Ethernet MAC. For platforms using device-tree this
usually means adding dma-ranges property to the bus the device node is
in.

Setting the clock delay from the device tree settings
rx-internal-delay-ps and tx-internal-delay-ps was broken:
- The expected value in the device tree is suppose to be a
delay in picoseconds, but the driver only allowed an array index.
- Driver converted this array index to the actual delay in
picoseconds and tried to apply this in the device register. This
however is not a valid register value. The actual logic here was
reversed, it converted an register representation of the delay to
the device tree delay in picoseconds.
Only when the internal delays were NOT configured in the device tree
and they default value of 7 (=2000ps) was used, a valid value was
loaded in the register.

There is no reason to setup ROM source if read_rom_hwaddr hook doesn't
exist or reading mac address fails. It is ending up with confusion about
mac address source.
It is nicely visible if you put mac address to DT as
local-mac-address = [ff ff ff ff ff ff];
but also save ethaddr to variables
setenv -f ethaddr 02:18:31:7e:3e:01
Before this patch U-Boot prints that source is ROM
Address in ROM is ff:ff:ff:ff:ff:ff
Address in environment is 02:18:31:7e:3e:01
After that source is DT:
Address in DT is ff:ff:ff:ff:ff:ff
Address in environment is 02:18:31:7e:3e:01

Board specific late init allows vendors to set up different device
or board specific env variables (like serial number, platform name).
In case this information is missing, u-boot will lack info regards
serial or platform.
To avoid this prior nvidia_board_late_init internal generic function
is called which fills required data. In this case platform name is
obtained from get_chip and serialno is filled with SoC id.
Though SoC id is not dedicated to be devices serial but it fits well
in case of restriction of data about device and since SoC is basically
a main chip of the device.
