[PATCH 1/6] i2c/pxa2xx: Don't touch ISAR on X86

[Sebastian Andrzej Siewior <bigeasy-hfZtesqFncYOwBW4kG4KsQ@public.gmane.org>]

The reset functions sets writes the slave address even in not slave
mode. I don't see any reason in writting it if slave mode is not
enabled.
Ben Dooks was conserned about making this change make it unavable on X86
where it is not available.
