Subject: [PATCH v2 -next] x86/platform/uv: Remove the unneeded extern keyword

The function declarations in bios.h are already marked extern, so remove
them in the definition.

This problem was caught by the sparse tool:
 function 'uv_bios_get_master_nasid' with external linkage has definition
 function 'uv_bios_get_heapsize' with external linkage has definition
 function 'uv_bios_install_heap' with external linkage has definition
 function 'uv_bios_obj_count' with external linkage has definition
 function 'uv_bios_enum_objs' with external linkage has definition
 function 'uv_bios_enum_ports' with external linkage has definition
 function 'uv_bios_get_geoinfo' with external linkage has definition
 function 'uv_bios_get_pci_topology' with external linkage has definition
