[Pdbg] [PATCH] libpdbg: Parse "compatible" property of fdt nodes

[Reza Arbab]

Set node->compatible appropriately when parsing the fdt. Otherwise, we
will later fail this assertion:

Found a POWER9 PPC host system
dt_expand[559]: FDT: Parsing fdt @0x100370d0
dt_expand[559]: FDT: Parsing fdt @0x10094330
Assertion failed: !target_is_virtual(node) (libpdbg/device.c: pdbg_targets_init_virtual: 660)
Aborted
