This library had timing issues when RATIO is high. To improve that, it was inserted a register slice into the library that is enabled only when required.

To avoid any latency on the current projects, SRC_REG_SLICE_EN is disabled by default.

Note: register slice definition is inside the DMA. I chose not to move the IP to a common folder to avoid another PR. Future solution need to consider moving this register slice library to common folder in the libraries.

Insert information about the SRC_REG_SLICE_EN, which enables the
register slice into the FIFO ASYM.
