Create two new functions to fetch mrc_cache data (replacing
mrc_cache_get_current):
- mrc_cache_load_current: fetches the mrc_cache data and drops it into
the given buffer. This is useful for ARM platforms where the mmap
operation is very expensive.
- mrc_cache_mmap_leak: fetch the mrc_cache data and puts it into a
given buffer. This is useful for platforms where the mmap operation
is a no-op (like x86 platforms). As the name mentions, we are not
freeing the memory that we allocated with the mmap, so it is the
caller's responsibility to do so.
Additionally, we are replacing mrc_cache_latest with
mrc_cache_get_latest_slot_info, which does not check the validity of
the data when retrieving the current mrc_cache slot. This allows the
caller some flexibility in deciding where they want the mrc_cache data
stored (either in an mmaped region or at a given address).

* Add ECC test code when DEBUG_RAM_SETUP is enabled
* Move ECC scrubbing after set_scrambling_seed() to be able to observe
what has been cleared in the test routine. If clearing happens
before set_scrambling_seed the data is XORed with a different PRN.
Data read from memory will look random instead of all zeros.
* ECC scrubbing must happen after dram_dimm_set_mapping()
The ECC logic is set to "normal mode" in dram_dimm_set_mapping(). In
normal mode the ECC bits are calculated and stored on write
transactions.
* Move method out of try_init_dram_ddr3().
This satisfies point 2 and point 3 of the list above.
