    xen/arm32: head: Fix build when using GAS 2.25.0
    
    GAS 2.25.0 throws multiple errors when building arm32/head.S:
    
    arm32/head.S: Assembler messages:
    arm32/head.S:452: Error: invalid constant (f7f) after fixup
    arm32/head.S:453: Error: invalid constant (f7f) after fixup
    arm32/head.S:495: Error: invalid constant (f7f) after fixup
    arm32/head.S:510: Error: invalid constant (f7f) after fixup
    arm32/head.S:514: Error: invalid constant (f7f) after fixup
    arm32/head.S:516: Error: invalid constant (f7f) after fixup
    arm32/head.S:633: Error: invalid constant (f7f) after fixup
    
    This makes sense because the instruction mov is only able to deal with a
    specific set of immediate (see "modified immediate constants in ARM
    instructions"). For any 16-bit immediate, the instruction movw should be
    used.
    
    It looks like newer version of GAS will seemly switch to movw if the
    immediate does not fit in the immediate encoding for mov. But we should
    not rely on this. So switch to movw.
