tegra20: move SDRAM param save to later in boot
Move warmboot_save_sdram_params() to later in the boot sequence. This code relies on devicetree to get the address of the memory controller and with upcoming changes for SPL boot it gets called early in the boot process when devicetree is not initialized yet.
