[PATCH v2 07/10] hw/i386: make explicit clearing of pch_rev_id

[Alex Bennée]

Some compilers (notably the Xenial gcc in Travis) fail to spot that
this will always be set if pch_dev_id != 0xffff. Given this is setup
code and using _Pragma to override is equally as ugly lets just remove
the doubt from the compilers mind.
