test: cmd: fdt: Test both string and integer arrays in 'fdt get value'

Browse source 
The 'fdt get value' subcommand now supports extraction of integer value
from integer arrays, add test for it, including a test for special case
unindexed integer array read, which is handled as hash and treated as a
long string instead of integer.
