ARM: tegra: dvfs: Don't power-down cluster if dfll bypass
If dfll is bypassed in legacy dvfs mode, CPU voltage during cluster
power-down entry/exit is at fixed level set by regulator h/w. This
level may not be high enough for current CPU rate. Hence, disabled
CPU G cluster power-down when dfll bypass is used.
