Fix fdt set command to conform to dts spec
The fdt set command was treating properties specified as <00> and <0011>
as byte streams, rather than as an array of cells. As we already have
syntax for expressing the desire for a stream of bytes ([ xx xx ...]),
we should use the <> syntax to describe arrays of cells, which are always
32-bits per element. If we imagine this likely (IMHO) scenario:
> fdt set /ethernet-phy@1 reg <1>
With the old code, this would create a bad fdt, since the reg cell would be
made to be one byte in length. But the cell must be 4 bytes, so this would
break mysteriously.
Also, the dts spec calls for constants inside the angle brackets (<>)
to conform to C constant standards as they pertain to base.
Take this scenario:
> fdt set /ethernet@f00 reg <0xe250000\ 0x1000>
The old fdt command would complain that it couldn't parse that. Or, if you
wanted to specify that a certain clock ran at 33 MHz, you'd be required to
do this:
Lastly, the fdt print code was rearranged slightly to print arrays of cells
if the length of the property is a multiple of 4 bytes, and to not print
leading zeros.
