ASoC: meson: axg-tdm: fix sample clock inversion 



The content of SND_SOC_DAIFMT_FORMAT_MASK is a number, not a bitfield,
so the test to check if the format is i2s is wrong. Because of this the
clock setting may be wrong. For example, the sample clock gets inverted
in DSP B mode, when it should not.

Fix the lrclk invert helper function
