bios32.c: Fix me in pci_fixup_it8152

Hey Russell and others,
Before I clean this fix me up I wanted to known how to define the values
as stated in the fix me in this function or if this is invalid as of the latest
kernel trees.
Cheers Nick

If you would like to fix it properly, then that's fine.  The comment
there says:

        /* FIXME: add defines for class 0x68000 and 0x80103 */
        if ((dev->class >> 8) == PCI_CLASS_BRIDGE_HOST ||
            dev->class == 0x68000 ||
            dev->class == 0x80103) {

The thing that's slightly confusing here is that dev->class contains
the class in bits 24..8, but also the programming interface in bits
7..0.

So, the comment is slightly wrong in that it's actually meaning
class 0x0680 with a programming interface of 0x00, and a class of
0x0801 with a programming interface of 0x03.

Your challenge is to _not_ add defines for these, but to use the
existing defines for these classes, and modify the code to use those
defines /without/ changing the effect of the checks.  Ignore that
there's no definitions of the programming interfaces - they can
stay as raw numbers.
