SDRAM initialization and test code from Pavel.
Integrated into the cli-test program as such:
cryptech> test sdram
Initializing SDRAM
Starting SDRAM test (n = 0)
Run sequential write-then-read test for the first chip
Run random write-then-read test for the first chip
Run sequential write-then-read test for the second chip
Run random write-then-read test for the second chip
Run interleaved write-then-read test for both chips at once
SDRAM test (n = 0) completed
SDRAM test completed successfully
