After the commit below the Broxton PLL IDs had an off-by-one error, so
fix this up. Also add a missing brace at intel_shared_dpll_init(), it
happened to compile only due to the way the IS_BROXTON macro is defined.

v2:
- remove debugging left-over

Fixes: a3c988ea ("drm/i915: Make SKL/KBL DPLL0 managed by the shared dpll code")
