[WATCHDOG] Fix declaration of struct smbios_entry_point in hpwdt
On my HP DL380 G5 system running a 64-bit kernel, loading the hpwdt driver causes a crash because the driver attempts to ioremap an invalid physical address. This is because the driver has an incorrect definition of the SMBIOS table entry point structure: the table address is only a 32-bit quantity, and making it a u64 means that the high-order 32 bits end up containing garbage. Correcting the structure definition fixes the driver so that it loads without any problems on my system.
