ASoC: tegra: tegra210-mixer: Use div_u64() for 64-bit division

A MIPS allmodconfig build with LLVM fails during modpost:

  ERROR: modpost: "__udivdi3"
  [sound/soc/tegra/snd-soc-tegra210-mixer.ko] undefined!

tegra210_mixer_configure_gain() divides a 64-bit BIT_ULL() value by the
fade duration. On 32-bit MIPS, clang emits a call to __udivdi3 for that
plain C division, but that compiler helper is not exported to modules.

Use div_u64() for the inverse duration calculation so the driver uses the
kernel's 64-bit division helper instead of emitting a compiler runtime
call.
