Removed leftover ccache instructions from debugging instability problems. Commented out required ccache instructions for when L1I cache returns in the future.

L2 cache at 100MHz now greatly increases performance. Attempted to create l1i and l1d cache, but becomes unstable and the issue is difficult to similate/replicate. Therefore, all l1 cache is now bypassed and the code can be found in l1cacheUnstable.v. As no l1 cache anymore, I removed some ccache statements to increase performance as this instruction currently does nothing.

Fixed instability by adding clear cache instruction during SPI transfer. No idea why this fixed the issue, as the I/O address range is above the limit for cache to work.
