York Sun 4961eafc25 armv8: layerscape: Update early MMU for DDR after initialization 
In early MMU table, DDR has to be mapped as device memory to avoid
speculative access. After DDR is initialized, it needs to be updated
to normal memory to allow code execution. To simplify the code,
dram_init() is moved into a common file as a weak function.

Overview
--------
QorIQ LS1012A FREEDOM (LS1012AFRDM) is a high-performance development
platform, with a complete debugging environment. The LS1012AFRDM board
supports the QorIQ LS1012A processor and is optimized to support the
high-bandwidth DDR3L memory and a full complement of high-speed SerDes ports.
