[PATCH v3 05/15] pylibfdt: Add Fdt.set_boot_cpuid_phys()

[Douglas Anderson <dianders@chromium.org>]

`FdtRo` exposes `boot_cpuid_phys()` to read the physical boot CPU ID
from the FDT header, and SWIG already wraps the underlying C function
`fdt_set_boot_cpuid_phys()`, but `class Fdt` lacked a corresponding
`set_boot_cpuid_phys()` method.

Add `Fdt.set_boot_cpuid_phys()` and test it in
`tests/pylibfdt_tests.py`.
