ASoC: rt1320: fix 32-bit link failure
A plain 64-bit division causes a link failure in some configurations:
ERROR: modpost: "__aeabi_uldivmod" [sound/soc/codecs/snd-soc-rt1320-sdw.ko] undefined!
Since this divides by a constant, using the div_u64() macro ends up
turning this into an efficient multiply/shift operation where possible.
In rt1320_calc_r0(), the open-coded shift seems a litle simpler.
Fixes: da1682d5e8b5 ("ASoC: rt1320: support calibration and temperature/r0 loading")
