This change is necessary to run litevideo, as old up converter was too slow to support
high bandwidth requirements of HDMI core.
Also old upconverter had two bugs:
* reading sequentially and non-sequentially would return data in the same order
* writing sequentailly and non-sequentially would return different memory state
test/test_adapter.py add new up converter test: test_up_converter_writes_not_sequential
This test checks if non-sequential writes to one dram word will create the same result as sequential writes
Add parameters for rx_buffer, tx_buffer and cmd_buffer depths
