dtc: Add program to convert dts files from v0 to v1

Browse source 
This patch adds a new utility program, convert-dtsv0, to the dtc
sources.  This program will convert dts files from v0 to v1,
preserving comments and spacing.  It also includes some heuristics to
guess an appropriate base to use in the v1 output (so it will use hex
for the contents of reg properties and decimal for clock-frequency
properties, for example).  They're limited and imperfect, but not
terrible.

The guts of the converter program is a modified version of the lexer
from dtc itself.
