net: sun8i-emac: Allow all RGMII PHY modes

So far all GBit users of the sun8i-emac driver were using the "rgmii"
PHY mode, even though this turns out to be wrong. It just worked because
the PHY driver doesn't do the proper setup (yet).
In fact for most boards the "rgmii-id" or "rgmii-txid" PHY modes are the
correct ones.

To allow the DTs to describe the phy-mode correctly, and to stay
compatible with Linux, at least allow those other RGMII modes in the
driver.

This avoids breakage if mainline DTs will be synced with U-Boot.

cmd: change suppress newline in echo command

By default the echo command emits its arguments followed by a line feed.

If any of the arguments contains the sub-string "\c", the line feed is
suppressed.

This does not match shells used in Linux and BSD where the first argument
has to be -n to suppress the line feed.

The hush shell interferes with the parsing of backslashes. E.g. in the
following command line quadruple backslashes are required for suppressing
the line feed:

for i in 1 2 3; do for j in 4 5; do echo \\\\c ${i}${j}; done; echo; done;

To avoid unexpected behavior the patch changes echo to use -n as first
argument to suppress the line feed.

mips: dts: switch to board defines for dtb for mtmips

Previous the dts files for gardena-smart-gateway-mt7688 and
linkit-smart-7688 are set to be built when mtmips is selected.

This can lead to a compilation error if another soc is added to this arch
with different dtsi files.

So it's better to build the dtb only if their board is selected.
