MLK-10945 ARM: imx: correct busfreq flow for i.mx6qp/dq/dl

When busfreq transit to low bus mode and back to normal
mode, the delay line settings should be restored, but the
software flow is entering the med setpoint path which is
NOT supported now, it will lead to incorrect delay line
settings for normal mode when busfreq is ever switching
to other mode and back to normal mode;

Store MMDC1 ODT setting as well and improve those MMDC
settings to align with ddr script in uboot, recommended
by design team.

During DLL On/Off switch, pre-charge command should be
only issued to those open banks, otherwise, some boards
busfreq stress test will be failed.
