This reverts commit edf0093732225c2fd0791c3864e9a3eef1f92f19 for cm_fx6 iMX.6 Solo module as it causes frequent (around 10 percent of power cycles) board's hangs.
These hangs happen in SPL when BSS is being initialized in SDRAM - it appear that variables from BSS contain trash values which lead to board hangs. Looks like that SDRAM doesn't yet finish initialization in these cases.
