[PATCH 02/11] PCI: Rename added to add_list

["Ilpo Järvinen" <ilpo.jarvinen@linux.intel.com>]

The resource fitting algorithm uses different names from the list
holding the optional sizes: added, add_head, add_list, and
realloc_head. 'add_list' sounds the most natural and some of the
related variables also use 'add' such as 'add_size'.

To reduce variation, rename 'added' and 'add_head' to 'add_list'.
Also rename some 'realloc_head' cases selectively to 'add_list'.

While it would be nice to rename every 'realloc_head' to 'add_list' for
consistency, it might create a backport headache with all to work going
into this algorithm that may need to be eventually backported. Thus,
it's better to leave 'realloc_head' as is for now.
