From: Helge Deller <deller@gmx.de>

commit 712a270d2db967b387338c26c3dc04ccac3fcec3 upstream.

The definitions for pdc_toc_pim_11 and pdc_toc_pim_20 are wrong since they
include an entry for a hversion field which doesn't exist in the specification.

Fix this and clean up some whitespaces so that the whole file will be in
sync with it's copy in the SeaBIOS-hppa sources.
