ASoC: tegra: tegra210-mixer: Reject too-short fade durations

DURATION_INV_N3 is computed from BIT_ULL(31 + prescalar) divided
by the configured duration, and then written as a 32-bit RAM value.

Durations of 32 samples or less overflow that value, so reject them
and advertise the valid range through the fade duration control.

Validate the ALSA integer control value as a long before storing it in
the driver's u32 duration field. Use a u32 temporary for duration RAM
writes because the largest valid inverse value can still exceed INT_MAX.
