nb/intel/i945/gma: Declare count variable outside 'for' loop

Building an image for the Lenovo X60 on Debian 8.5 (jessie) with GCC 4.9.2,
compilation fails with the error below.

```
$ gcc --version
gcc (Debian 4.9.2-10) 4.9.2
[…]
$ make # lenovo/x60 with native graphics initialization
[…]
    CC         ramstage/northbridge/intel/i945/gma.o
src/northbridge/intel/i945/gma.c: In function 'probe_edid':
src/northbridge/intel/i945/gma.c:570:2: error: 'for' loop initial declarations are only allowed in C99 or C11 mode
  for (int i = 0; i < 8; i++) {
  ^
src/northbridge/intel/i945/gma.c:570:2: note: use option -std=c99, -std=gnu99, -std=c11 or -std=gnu11 to compile your code

make: *** [build/ramstage/northbridge/intel/i945/gma.o] Error 1
```

Fix this by declaring the count variable outside the 'for' loop.
