arm64: dts: qcom: Add #{address,size}-cells to Chromium-based /firmware

Chromium/Depthcharge bootloaders may dynamically add a few device nodes
to a system's DTB under a /firmware node. A typical DT looks something
like the following:

/ {
        firmware {
                ranges;

                coreboot {
                        compatible = "coreboot";
                        reg = <...>;
                        ...;
                };
        };
};

Notably, the /firmware node has an empty 'ranges', but does not have
address/size-cells.

Commit 6e5773d52f4a ("of/address: Fix WARN when attempting translating
non-translatable addresses") started requiring #address-cells for a
device's parent if we want to use the reg resource in a device node.
This leads to errors like the following:

[    7.763870] coreboot_table firmware:coreboot: probe with driver coreboot_table failed with error -22

Add appropriate #{address,size}-cells to work around the problem.

Note that Google has also patched the Depthcharge bootloader source to
add {address,size}-cells [1], but bootloader updates are typically
delivered only via Google OS updates. Not all users install Google
software updates, and even if they do, Google may not produce updated
binaries for all/older devices.
