drivers/ddr/fsl: Enable detection of one DDR controller operation for LSCH3

Freescale LSCH3 platforms use two DDR controlers interleaving mode out of
reset. It can be configured to disable one controller. To support this
operation, the driver needs to detect and skip the disabled controller.

By default the bstopre value has been set to 0x100, used to be 1/4
value of refint. Modern DDR has increased the refresh time. Adjust
to 1/4 of refresh interval dynamically. Individual board can still
override this value in board ddr file, or to use auto-precharge.

driver/ddr: Restruct driver to allow standalone memory space

U-boot has been initializing DDR for the main memory. The presumption
is the memory stays as a big continuous block, either linear or
interleaved. This change is to support putting some DDR controllers
to separated space without counting into main memory. The standalone
memory controller could use different number of DIMM slots.
