[PATCH for-7.2 09/10] device_tree.c: add fdt_print_property() helper


From: Daniel Henrique Barboza
Subject: [PATCH for-7.2 09/10] device_tree.c: add fdt_print_property() helper
Date: Fri, 22 Jul 2022 17:00:06 -0300

We want to be able to also print properties with 'info fdt'.

Create a helper to print properties based on the already existing code
from fdt_print_node().
