efi eliminate bad section references

Randy please double check especially this one.
there may be a better solution.

Fix efi section references:
remove __initdata for struct efi efi_phys
and struct efi_memory_map memmap

Error: ./arch/i386/kernel/efi.o .text refers to 000000d3 R_386_32 .init.data
Error: ./arch/i386/kernel/efi.o .text refers to 000000ff R_386_32 .init.data

efi_memmap_walk (which is not __init nor static)
accesses both efi_phys and memmap.

(adding Matt Domsch to cc:)

'memmap' can be used after init, so remove __initdata from it certainly looks correct to me.

Regarding efi_phys:
'efi_get_time' can be called after init (that "inline ... _init" on it is confusing to me), and it calls phys_efi_get_time(), which uses 'efi_phys', so efi_phys should not be marked as __initdata.

OTOH, phys_efi_set_virtual_address_map() can be marked as __init. You could add that as an efficiency measure.

so
