hpt366: print the real chip name at startup
- Rework the driver setup code so that it prefixes the driver startup messages with the real chip name. - Print the measured f_CNT value and the DPLL setting for non-HPT3xx chips as well. - Claim the extra 240 bytes of I/O space for all chips, not only for those having PCI device ID of 0x0004.
