If the clock framework can't figure out how to enable a clock, return -EINVAL to indicate that the clock cannot be enabled. Previously the code returned 0, which indicated success. Also fix the "clock.c: Enable for dpll_ck without enable code" boot warning by marking dpll_ck as ALWAYS_ENABLED. This is not technically true, since the DPLL can be bypassed; but since we currently have no software infrastructure to control it directly, ALWAYS_ENABLED is a sufficient fiction for dpll_ck.
