Avoid the use of an uninitialized stack variable when the powerpc device tree
bootargs property is either missing or incorrectly defined. This also makes
CONFIG_CMDLINE work properly under these conditions. This change adds a test
for the existence of the bootargs property.
early_init_dt_scan_chosen() tests for a zero length bootargs property in its
CONFIG_CMDLINE processing, but the current implementation of
of_get_flat_dt_prop() doesn't assign a value to the length when no property is
found. Since an automatic variable is used, a stale value from the stack will
be used in the test.
