C90: correct initialisation of ARM SIMD register

arm/palette_neon_intrinsics.c: change the initialisation of the "opaque black" standard PLTE filler to be in-line rather than using a C99 style {} initializer which calls functions. This change also reduces the number of function calls required from 4 to 2. Signed-off-by: John Bowler <[email protected]>
