Purge legacy HTIF things
...
The SCR file is gone, too, because it was tightly coupled. The
general concept could be revived as a module that somehow connects
to the debug module.

Dynamically compute number of L1 client channels
...
Until now, the number of L1 client channels was set statically in the
configuration. This static configuration also assumed the same number of
cached and uncached channels per tile. As we plan to move towards
heterogenous multicore systems, this restriction should be removed.
This commit changes the generator so that number of channels per tile
can be independently set (using cde.Parameters.alterPartial).
The OuterMemorySystem will dynamically compute the number of cached and
uncached channels by summing the number of each kind of channel per core.

Changes to prepare for switch to TileLink interconnect
...
We are planning on switching to a TileLink interconnect throughout and
convert to AXI only on the very edge. Therefore, we need to get rid of
all the existing AXI masters other than the TileLink to AXI converter.
* Get rid of DMA engine for now
* Connect RTC to TileLink interconnect instead of AXI interconnect
