driver/ddr/fsl: Add built-in memory test for DDR4 driver Add built-in memory test to catch errors after DDR is initialized, before any other transactions. To enable this test, define CONFIG_FSL_DDR_BIST. An environmental variable "ddr_bist" is checked before starting test. It takes a while (several seconds) depending on system memory size.
