Simona Toaca c9a8f673e0 imx9: Add support for saving DDR training data to NVM

DDR training data can be saved to NVM and be available
to OEI at boot time, which will trigger QuickBoot flow.

U-Boot only checks for data integrity (CRC32), while
OEI is in charge of authentication when it tries to
load the data from NVM.

On iMX95 A0/A1, 'authentication' is done via another
CRC32. On the other SoCs, authentication is done by
using ELE to check the MAC stored in the ddrphy_qb_state
structure.

Supported platforms: iMX94, iMX95, iMX952 (using OEI)
Supported storage types: eMMC, SD, SPI flash.
