[PATCH] ASoC: fsl_ssi: Use u32 variable type when using regmap_read()

[Fabio Estevam <festevam@gmail.com>]

From: Fabio Estevam <fabio.estevam@nxp.com>

Convert the sisr and sisr2 variable types to u32 to avoid the following
sparse warnings:

sound/soc/fsl/fsl_ssi.c:391:42: warning: incorrect type in argument 3 (different base types)
sound/soc/fsl/fsl_ssi.c:391:42:    expected unsigned int *val
sound/soc/fsl/fsl_ssi.c:391:42:    got restricted __be32 *<noident>
sound/soc/fsl/fsl_ssi.c:393:17: warning: restricted __be32 degrades to integer

sound/soc/fsl/fsl_ssi.c:396:50:    got restricted __be32 [usertype] sisr2
sound/soc/fsl/fsl_ssi.c:398:42: warning: incorrect type in argument 2 (different base types)
sound/soc/fsl/fsl_ssi.c:398:42:    expected unsigned int [unsigned] [usertype] sisr
sound/soc/fsl/fsl_ssi.c:398:42:    got restricted __be32 [addressable] [usertype] sisr

In other places where regmap_read() is used a u32 variable is passed
to store the register read value, so do the same here as well.

regmap API already takes care of endianness, so the usage of u32 is safe.
