[PATCH] HPT3xx: print the real chip name at startup

Hello.

- 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.

MBR, Sergei
