UPSTREAM: ASoC: da7219: Disallow unsupported 32KHz clock setting in set_dai_sysclk()

The PLL function was updated to disallow 32KHz in
commit 501f72e9c520 ("ASoC: da7219: Remove support for 32KHz PLL mode"),
but set_dai_sysclk() was missed and still permits it. This patch resolves
that discrepancy.
