ASoC: cs53l30: Correct clock inversion check

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

SND_SOC_DAIFMT_IB_NF = 0x3 (11b) | SND_SOC_DAIFMT_IB_IF = 0x4 (100b)
creates a mask 0x7 (111b) which also includes SND_SOC_DAIFMT_NB_IF
= 0x2 (10b).

So this patch uses the traditional way to check the clock inversion.
