Replaced the Cirrus Logic code with the latest code from TheCollector1995 - the CL-GD 5428 is now fully working, as is the CL-GD 5429;
Minor clean-up in the AHA/BusLogic BIOS commands code;
Slightly rewritten mem_readb_phys_dma() and mem_writeb_phys_dma().
Re-worked the system pathnames (pc.c), renamed cfg_path to usr_path.
Other small things here and there.
Logitech bus mouse re-worked, should be OK now.
