i386: Fix broken mmiocfg accesses
Commit 3320ad994afb2c44ad34b3b34c3c5cf0da297331 broke mmio config space accesses totally on i386 - it dropped the "reg" offset to the address. Cc: dean gaudet <dean@arctic.org> Cc: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
