CHROMIUM: drm: nouveau: initialize variables in nv40_pm

These variables are implicitly initialized by being passed as pointers
into nv40_calc_pll().  However, the compile still generates these
warnings:

nv40_pm.c:163:41: warning: 'log2P' may be used uninitialized in this
function
nv40_pm.c:164:38: warning: 'M2' may be used uninitialized in this
function
nv40_pm.c:164:45: warning: 'M1' may be used uninitialized in this
function
nv40_pm.c:164:25: warning: 'N2' may be used uninitialized in this
function
nv40_pm.c:164:51: warning: 'N1' may be used uninitialized in this
function

BUG=chromium-os:5542
TEST=emerge-x86-generic chromeos-kernel, make sure these warnings don't
appear.
