mx6: ddr: Restore ralat/walat in write level calibration
The current DDR write level calibration routine always overwrite
the ralat/walat fields to their maximum value, just save
the existing values at the beginning of the calibration routine
and restore it at the end.
In case the delay is estimated by the user to be more than one cycle the
walat should be configured according to that, this is not
automatically done. From the i.MX6 RM:
The user should read the results of the associated delay-line at
MPWLDECTRL#[WL_DL_ABS_OFFSET#] and in case the user estimates that the
reasonable delay may be above 1 cycle then the user should indicate it at
MPWLDECTRL#[WL_CYC_DEL#]. Moreover the user should indicate it in
MDMISC[WALAT] field. For example, if the result of the write leveling calibration
is 100/256 parts of a cycle, but the user estimates that the delay is above 2 cycles
then MPWLDECTRL#[WL_CYC_DEL#] should be configured to 2, so the total
delay will be 2 and 100/256 parts of a cycle
Probably it would just possible to not overwrite the mdmisc register in
the first place, since this is not present in the write_level_calib() example
in NXP AN4467 nor in the i.MX6 RM (44.11.6.1 Hardware Write Leveling

This commit broke environment on literally every board I have access

The problem I observe with this patch is that saved environment in
either SPI NOR or eMMC is never used, the system always falls back
to default environment. The 'saveenv' command does succeed, but then
after reset, the default env is again used.
Furthermore, the commit introduced duplicate code in env_init(), this:
"
