Exynos5250: make vendor enums in the timing array more debuggable.

The timing array is crucial to proper operation of DRAM.

Getting a valid pointer to it is hence very important. Unfortunately,
the constants chosen for the vendor were '1', and '2', (this in a
32-bit word) which in a debug print makes it almost impossible to tell
if you've got a misaligned pointer. Note: coreboot people did not
choose them :-)

So, give them values which are extremely unlikely to occur elsewhere
in the array (or in memory, for that matter).

Given the frequency with which this check occurs, i.e. once, I would
much prefer strings but I expect I'd get shouted down on that
one. Constants in this case are an almost useless optimization but
we'll go with them for now. Note no space is saved by not using
strings: there's an entire function somewhere devoted to mapping the
enum to a string!

Debug prints of pointers to structs in this array are now far more
useful than they were.

See snarky comment in the code (left there to make sure nobody gets
tempted to get fancy again). Comment now less snarky.

This is tested on google snow to the point that the DRAM works.
