software/bios/sdram: for now desactivate random on address test since it seems to trigger a L2 cache or LASMIcon bug on at least de0nano/minispartan6
...
Memtest sometimes reports 1 or 2 errors with de0nano/minispartan6 on this new test when used with LASMICON. Minicon seems fine. We will have to investigate on this issue.

software/bios/sdram: add random addressing to memtest
...
testing memories with linear access is not good enough. Adding random addressing allow us to detect more eventual issues on our L2 cache or SDRAM controller.

software/bios/memtest: add data bus test (0xAAAAAAAA, 0x55555555) on a small portion of the test zone.
...
we now need to add another random addressing test to avoid linear access on L2 cache

sdram: improve memtest by adding 2 different writes/reads
...
doing only a write and read is not enough: if we reloaded a fpga with write that is not working after functional fpga, it would not trigger an error.
