[PATCH v2 2/8] parallels: Move BAT entry setting to a separate function

[Alexander Ivanov]

Will need to set BAT entry in multiple places.
Move the code of settings entries and marking relevant blocks dirty
to a separate helper parallels_set_bat_entry.

v2: A new patch - a part of a splitted patch.
