From: Roland Gaudig <roland.gaudig@gaudig.com>

In cases where there exists an unused and unformatted spare partion which
shall be activated by a later update, it is necessary to format such a
partition even if the partition table has not been altered.

Therefore, this commit introduces a new configuration option
CONFIG_DISKFORMAT_IGNORE_PT_CHANGE. If this option is activated a partition
will be formatted anyway if requested by the sw-description. No matter if
the partition table has been changed or not.
