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.
