ASoC: fsl_ssi: Redefine RX and TX macros
The RX and TX macros were defined implicitly and there was a potential risk if someone changes their values. Since they were defined to index the array ssi->regvals[2], this patch moves these two macros to fsl_ssi.c, closer to its owner ssi->regvals. And it also puts some comments here to limit their value within [0, 1]. Signed-off-by: Nicolin Chen <nicoleotsuka@gmail.com> Tested-by: Caleb Crome <caleb@crome.org> Tested-by: Maciej S.
