The existing bootph binding is defined such that properties in a
subnode are also implied in the supernode also, as in this example:

   buttons {
      /* bootph,pre-ram is implied by btn1 */
      compatible = "gpio-keys";

      btn1 {
         bootph,pre-ram;
         gpios = <&gpio_a 3 0>;
         label = "button1";
         linux,code = <BTN_1>;
      };

Provide an option to implement this in fdtgrep.

The h_include() function includes a piece which checks if a node
contains a property being searched for. Move this into its own
function to reduce the size of the h_include() function.

The code to invert the match in h_include() is a bit convoluted.
Simplify it by using disp->invert only once.

Copy the comment from fdt_first_region() so that it is clear what value
this function returns.

Signed-off-by: Simon Glass <sjg@chromium.org>

The function name is actually fdtgrep_find_regions() so update the name
in comments accordinging.

Two of the flags are out of order, so fix this.

Also adjust the ordering of one flag in the main switch()

Align the code with the upstream version at fdt-tools which had a few
tweaks before being applied.
