This PR contains a collection of improvements to the soc peripheral infrastructure and the SoC in general assembled from the last couple of tapeouts. Here is a list of changes:

  • The udma subsystem has been wrapped in a different repo and now only exposes struct based IO signals for simpler through-hierarchy routing
  • The old apb_gpio peripheral has been replaced with the more modern and feature enhanced version from pulp-platfrom/gpio
  • Externalization of the clock generation logic
  • Removal of unused signals and fixing of various linter warnings
  • Externalization of reset synchronization

This PR introduces breaking changes to the top-level interface of pulp-soc.

- Renamed fc_eu signals to fc_interrupts to make a clear distinction between
  events and interrupts.
- Removed old APB crossbar and replaced it with integrated crossbar in AXI-lite
  to APB converter. Moved address definitions from peripheral_bud_defines to soc_mem_maps.svh
