[PATCH] powerpc/fsl-pci: Correct use of ! and &

[Himangi Saraogi <himangi774@gmail.com>]

In commit ae91d60ba88ef0bdb1b5e9b2363bd52fc45d2af7, a bug was fixed that
involved converting !x & y to !(x & y).  The code below shows the same
pattern, and thus should perhaps be fixed in the same way.

The Coccinelle semantic patch that makes this change is as follows:

// <smpl>
@@ expression E1,E2; @@
(
  !E1 & !E2
|
- !E1 & E2
+ !(E1 & E2)
)
// </smpl>

This is not tested and clearly changes the semantics, so it is only
something to consider.
