[patch -resend] drm/i915/bios: cleanup return type of intel_parse_bios()

[Dan Carpenter <dan.carpenter@oracle.com>]

These are unintuitive.  These are type bool and return -1 casted to true
on failure.  Let's just make it return an int.  The callers don't care,
but let's change this as a cleanup.

Originally sent on Wed, Mar 28, 2012.  This one is prossibly my fault.
I assumed these would be in the same tree, but apparently I should have
broken them out.  Daniel acked the patch and told me that if I wanted to
I could break it up and he could merge part (or all of it?).  I have no
problem with redoing patches but I understood that to mean it was going
to go through a someone else's tree with his Acked-by.  If you give me
an option, of course I'm going to pick the laziest one.  That is my firm
promise and commitment.
