Revert "mx6: ddr: Allow changing REFSEL and REFR fields" 

This reverts commit edf0093732 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.
