MLK-12861-1 ARM: imx: support runtime clock management on i.mx7d when M4 is enabled
For i.MX7D, current runtime clock management code will skip all
PLL/PFD/GATE enable/disable when M4 is enabled, this is NOT good
for power number in low power idle and audio playback, as M4 only
uses one high speed PFD which is from system PLL, it is never
disabled runtimely, so we can just enable the hardware operation of
PLL/PFD/GATE for A7.
