x86: extend and use x86_quirks to clean up NUMAQ code
add these new x86_quirks methods:
int *mpc_record;
int (*mpc_apic_id)(struct mpc_config_processor *m);
void (*mpc_oem_bus_info)(struct mpc_config_bus *m, char *name);
void (*mpc_oem_pci_bus)(struct mpc_config_bus *m);
void (*smp_read_mpc_oem)(struct mp_config_oemtable *oemtable,
unsigned short oemsize);
... and move NUMAQ related mps table handling to numaq_32.c.
also move the call to smp_read_mpc_oem() to smp_read_mpc() directly.
Should not change functionality, albeit it would be nice to get it
tested on real NUMAQ as well ...
