This adds some more uses of M_PI to i915_fpc_translate.c, before the
definition of M_PI it makes for the benefit of <math.h> which don't define
M_PI. See [1].

Attached is a patch which fixes this by moving the definition of M_PI.

I'm not sure why this file and the few others which do this, don't include
compiler.h for the definition M_PI there...
