[PATCH] ASoC: wm5102: Use get_unaligned_be16() for dac_comp_coeff

[Richard Fitzgerald]

Replace the two-step copy-and-convert in
wm5102_out_comp_coeff_put() with get_unaligned_be16(). Apart from
looking nicer, it avoids this sparse warning:

wm5102.c:687:35: sparse: sparse: cast to restricted __be16
