b56b46b7d1 icache: Set associative icache
This adds support for set associativity to the icache. It can still
be direct mapped by setting NUM_WAYS to 1.

The replacement policy uses a simple tree-PLRU for each set.

This is only lightly tested, tests pass but I have to double check
that we are using the ways effectively and not creating duplicates.
